Description
スキャンドライバ103は、PDP101の走査電極Yの各電位を個別に変化させる。特に、走査パルス電圧を走査電極Yに対して所定の順番で印加する。
サステインドライバ102は、高い出力電圧レベルが要求されることから、高耐圧素子を用いて回路が構成される。また、回路の電源効率を高めるために、出力電圧波形がハイレベルの時のみ回路動作が有効に機能するように、出力振幅を制御回路の電源ラインに帰還するブートストラップ回路を採用することが多い。
ここで、サステインドライバ102は集積化した半導体装置で構成されており、電源端子VCC、接地端子GND、高電位側電源端子VB、出力端子HO、および低電位側端子VSなどは半導体装置の外部端子であって、入力回路1、レベルシフト回路2、受信回路3、基準電圧回路20、保護回路7および出力回路18が半導体装置内に集積化されている。
図5において出力MOSトランジスタ37がオンしている間は、低電圧側電源VCCからダイオード38のVF≒0.7ボルトだけ低下した電圧が容量39に供給される。出力MOSトランジスタ36がオンしている間はVS端子がほぼHV電圧まで上昇し、高電圧電源VBは“VS+VCC−0.7”ボルトとなる。出力MOSトランジスタ36,37のオン時間、容量39の容量値によって高電圧電源VBは変動する。
図5では、MOSトランジスタ22と抵抗21の直列回路によって構成する簡単な基準電圧回路20を用いており、基準電圧VrefがMOSトランジスタ22の閾値電圧Vtに依存する。MOSトランジスタ22の閾値電圧Vtの大きさは、MOSトランジスタの製造ばらつきによって異なったり、固有の温度特性を有していたりしている。そのことが、半導体装置毎に保護回路7の検出感度が異なったり、周囲温度によって検出感度が変動したりする原因となり、半導体装置の回路動作を保証しにくい、という問題がある。
(実施の形態1)
図1と図2は本発明の(実施の形態1)を示す。
図1に示すサステインドライバは、入力回路1とレベルシフト回路2は、電源端子VCCと接地端子GNDとの間に印加される電源電圧により動作する。
入力回路1を介して入力される入力信号INは、レベルシフト回路2を介して高耐圧フローティングブロック19内の受信回路3に入力され、その受信回路3の出力信号によって、出力回路18が駆動され、高電圧の出力信号を出力端子HOから出力する。
また、基準電圧回路17は、NPNバイポーラトランジスタ10,12のコレクタを高耐圧フローティングブロック19の高電位側電源端子VBに接続して回路構成されることから、NPNバイポーラトランジスタ10,12のトランジスタ活性領域を高耐圧フローティングブロック19の素子形成領域26内にその他の半導体素子と一緒に形成することが可能になる。
次に、電源電圧が低下した時に作動する保護回路を有した半導体装置について説明する。
次に、過熱保護回路を有した半導体装置について、図3を用いて説明する。
図3は本発明の(実施の形態3)を示す回路構成であり、受信回路3、基準電圧回路17、過電圧保護用の保護回路7および出力回路18に関する説明は省略する。
