Abstract
Description
第1の実施形態に係る半導体集積回路50は、図1に示すように、駆動対象として、例えば電力変換用ブリッジ回路の一相分である電力変換部60を駆動する高耐圧のパワーICである。電力変換部60は、高圧側スイッチング素子S1と、低圧側スイッチング素子S2とを直列に接続して出力回路を構成している。図1においては、高圧側スイッチング素子S1及び低圧側スイッチング素子S2がそれぞれIGBTである場合を例示しているが、高圧側スイッチング素子S1及び低圧側スイッチング素子S2はIGBTに限定されるものではなく、MOSFET等の他の電力用スイッチング素子でも構わない。高圧側スイッチング素子S1には還流ダイオードFWD1が並列に逆接続され、低圧側スイッチング素子S2には、還流ダイオードFWD2が並列に逆接続されている。なお、高耐圧側スイッチング素子S1と還流ダイオードFWD1、及び低耐圧側スイッチング素子S2と還流ダイオードFWD2それぞれの代わりに、IGBTとFWDを1チップに集積させた逆導通IGBTを用いてもよい。
第2実施形態に係る半導体集積回路の回路構成は、図1に示した実施形態に係る半導体集積回路の回路構成と同様である。第2実施形態に係る半導体集積回路は、図8に示すように、VS電位を基準電位として動作するハイサイド回路領域101と、GND電位を基準電位として動作するローサイド回路領域102とを1チップに備える。第2実施形態に係る半導体集積回路は、ローサイド回路領域102に、図1に示したレベルシフト回路42の保護ダイオード70に加えて、図1に示したローサイド駆動回路47のpMOSトランジスタ48及びnMOSトランジスタ49が設けられている点が、第1実施形態に係る半導体集積回路と異なる。
第3実施形態に係る半導体集積回路の回路構成は、図1に示した実施形態に係る半導体集積回路の回路構成と同様である。第3実施形態に係る半導体集積回路は、図12に示すように、VS電位を基準電位として動作するハイサイド回路領域101と、GND電位を基準電位として動作するローサイド回路領域102とを1チップに備える。ハイサイド回路領域101の構成は、図2に示した第1実施形態に係る半導体集積回路のハイサイド回路領域101と同様であるので、重複した説明を省略する。
上記のように、本発明は第1〜第3実施形態によって記載したが、この開示の一部をなす論述及び図面は本発明を限定するものであると理解すべきではない。この開示から当業者には様々な代替実施形態、実施例及び運用技術が明らかとなろう。
