CIRCUITO INTEGRADO DE GESTIÓN DE ALIMENTACIÓN ELÉCTRICA PROGRAMABLEINTEGRATED CIRCUIT OF PROGRAMMABLE ELECTRIC POWER MANAGEMENT

OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION

La presente invención se refiere a un circuito integrado de gestión de alimentación eléctrica re-programable, cuya finalidad es la de permitir ofrecer un sistema de alimentación de alta versatilidad, que pueda programarse para diferentes aplicaciones, funciones concretas y diferentes secuencias de inicio o encendido, todo ello con unas mínimas dimensiones.The present invention relates to a re-programmable integrated power management circuit, whose purpose is to allow to offer a highly versatile power system, which can be programmed for different applications, specific functions and different start or start sequences, all with a few dimensions.

La invención se sitúa pues en el ámbito de los sistemas de gestión de alimentación eléctrica de dispositivos en los que existe una disponibilidad de espacio reducida y es necesaria una versatilidad de la alimentación eléctrica.The invention is therefore in the field of power supply management systems of devices where there is reduced space availability and a versatility of the power supply is necessary.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Los sistemas convencionales de alimentación están diseñados cada uno para una aplicación concreta, un aplicativo concreto, un procesador concreto o una función concreta, y estos no pueden ser modificados en su lógica interna.Conventional feeding systems are each designed for a specific application, a specific application, a specific processor or a specific function, and these can not be modified in their internal logic.

Consecuentemente, en los desarrollos actuales, el diseñador del dispositivo electrónico de que se trate se ve obligado a utilizar un sistema de alimentación distinto cada vez, teniendo que añadir en sus circuitos una cantidad de sistemas de gestión independientes que ocupan espacios e incrementan los costes y además hace que la curva de aprendizaje a la hora de diseñar empiece de cero con cada diseño, dejando el hardware en mano de un estudio metódico de funcionamiento basado siempre en umbrales de seguridad que no permiten una adaptación correcta de los integrados en los aplicativos y la modificación en caso de error.Consequently, in the current developments, the designer of the electronic device in question is forced to use a different feeding system each time, having to add in its circuits a number of independent management systems that occupy spaces and increase costs and It also makes the learning curve when designing starts from scratch with each design, leaving the hardware in hand for a methodical study of operation based always on security thresholds that do not allow a correct adaptation of the integrated in the applications and the modification in case of error.

De la misma forma a los fabricantes de microprocesadores se les plantea cada vez que crean un microprocesador, el sobrecoste y reto de crear un BLOQUE DE ALIMENTACIÓN para su micro, creando un diseño de referencia y obligando al usuario a seguirlo. Por norma general este BLOQUE DE ALIMENTACIÓN está pensado para suplir las características más básicas del silicio que el propio fabricante ha desarrollado, puesto que no sabe cuál será el Aplicativo final.In the same way, microprocessor manufacturers are asked each time they create a microprocessor, the extra cost and challenge of creating a POWER SUPPLY BLOCK. for your micro, creating a reference design and forcing the user to follow it. As a general rule, this POWER SUPPLY BLOCK is designed to supply the most basic silicon characteristics that the manufacturer has developed, since he does not know which will be the final application.

Consecuentemente, y por norma general, esto conlleva sobrecostes en el diseño final pues hay que gestionar la energía, siempre.Consequently, and as a general rule, this entails extra costs in the final design, since energy must be managed, always.

DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION

El circuito integrado de gestión de alimentación eléctrica o BLOQUE DE ALIMENTACIÓN programable que se preconiza resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta.The programmable integrated power management circuit or programmable POWER BLOCK solves the above problems in a fully satisfactory manner.

Para ello, y de forma más concreta, La solución que se propone es un circuito integrado de gestión de alimentación eléctrica programable, es decir un BLOQUE DE ALIMENTACIÓN compuesto por las partes naturales que determinan un BLOQUE DE ALIMENTACIÓN , como son convertidores de potencia o Bucks, reguladores de voltaje LDO ( low drop Regulator), módulo de reloj en tiempo real (RTC), función de Carga de batería, módulo de control del nivel de batería, cargadores de batería, conversores DCDC ( de corriente continua a corriente continua), ADC ( conversores analógicos-digitales) y buses de comunicación, gestionado todo por un bloque de microprocesador, que es capaz de ser programado para crear en cada uno de los casos en los que se aplique una secuencia de inicio lógica programada para que el procesador o el aplicativo funcione.To do this, and more specifically, The solution proposed is an integrated programmable power management circuit, ie a POWER BLOCK composed of the natural parts that determine a POWER SUPPLY BLOCK, such as power converters or Bucks. , LDO (low drop Regulator) voltage regulators, real-time clock module (RTC), battery charging function, battery level control module, battery chargers, DCDC converters (direct current to direct current), ADC (analog-digital converters) and communication buses, all managed by a microprocessor block, which is capable of being programmed to create in each of the cases in which a programmed logical start sequence is applied so that the processor or the application works.

A partir de esta estructuración, el BLOQUE DE ALIMENTACIÓN, con altas funcionalidades, también es capaz de proporcionar la suficiente potencia como para gestionar los periféricos del sistema, evitando así componentes de alimentación externos, y permitiendo así una gestión muy inteligente del consumo, pues el microcontrolador permite la gestión en todos los modos energéticos, incluso con el microprocesador principal apagado.From this structuring, the POWER SUPPLY BLOCK, with high functionalities, is also able to provide enough power to manage the peripherals of the system, thus avoiding external power supply components, and thus allowing a very intelligent consumption management, since the microcontroller allows management in all energy modes, even with the main microprocessor off.

De forma más concreta, el microcontrolador es programable de forma independiente, y no necesitar ser programado desde un aplicativo ya encendido, siendo totalmente autónomo, y una vez programada la secuencia, es capaz interaccionar con el botón de encendido (power on) y crear todo el proceso de inicio, encendiendo cada uno de los LDO ( low drop Regulator) o bucks de forma correcta.More specifically, the microcontroller is programmable independently, and does not need to be programmed from an already lit application, being totally autonomous, and Once the sequence is programmed, it is able to interact with the power on button and create the entire start process, turning on each LDO (low drop Regulator) or bucks correctly.

Los umbrales de alimentación del circuito estarían en voltaje de entrada de los 3V a los 6V y los de salida de 0,8V a 5V.The power thresholds of the circuit would be in the input voltage from 3V to 6V and the output from 0.8V to 5V.

El sistema tiene un bus de comunicación con el AP ( Procesador externo) para la regulación de voltaje, en caso de que el procesador la utilice, este se puede adaptar y programar al protocolo que AP necesite, como puede ser el DVS, SVI, VID, etc...The system has a communication bus with the AP (external processor) for voltage regulation, in case the processor uses it, it can be adapted and programmed to the protocol that AP needs, such as DVS, SVI, VID , etc...

Esto también permite hacer cambios en la secuencia de inicio incluso después de haber creado el dispositivo.This also allows changes to the startup sequence even after the device has been created.

Por su parte, el microcontrolador gestiona todo el bloque de alimentación pero el BLOQUE DE ALIMENTACIÓN tiene su propia lógica programable aparte, lo que permite que el BLOQUE DE ALIMENTACIÓN se comporte de forma genérica de un modo que el microcontrolador luego puede cambiar y gestionar.For its part, the microcontroller manages the entire power block but the POWER BLOCK has its own separate programmable logic, which allows the POWER BLOCK to behave in a generic way in a way that the microcontroller can then change and manage.

Finalmente cabe destacar el hecho de que el BLOQUE DE ALIMENTACIÓN sea programable se puede presentar de dos maneras:Finally, it should be noted that the FOOD BLOCK can be programmed in two ways:

• Como un BLOQUE DE ALIMENTACIÓN programable en un solo silicio.• As a FOOD BLOCK programmable in a single silicon.

• Como un BLOQUE DE ALIMENTACIÓN programable con bobinas y discretos incluido, de tamaño superior pero listo para ser instalado.• As a programmable POWER BLOCK with coils and discrete included, larger in size but ready to be installed.
