Abstract
Description
この特許は、ディスクリートパワー半導体デバイスに関し、より特定的には、ディスクリート半導体デバイス内の電流を精度良く検知する方法に関する。
パワー半導体デバイスは、今日において、電源、電圧レギュレータ、DC/DCコンバータ、モータドライブ、安全スイッチ、バッテリ切断スイッチ、省電力負荷スイッチ、電流リミッタ、ポート保護デバイス、オーディオアンプなどを含む電気システムの幅広い分野において用いられている。
・VDSの検知
・磁流の検知
・集積電流ミラー
以下、これらの検知技術、それらの動作原理、回路の実現および電気的特性について説明する。
AVは、アンプ5の閉ループ電圧のゲインであり、Voffsetは、アンプ内のある任意の電圧オフセットであり、極性は正または負である。抵抗型電流検知回路は、信号Voを、PWM制御、スリューレート制御、電流制限などのアナログ電気回路を含み得る制御電気回路に送る。
Vo=Av(I・RDS(on)+Voffset)∝I
によって与えられる。
I2=I1/n
である。
RDSA=BVn
で与えられる。100Vよりも下では、アバランシェの臨界電場は、n≒1.0となるようにドーピングの係数であり、その結果、デバイスのオン抵抗は、その降伏電圧により特選的に依存する。よって、縦型DMOSトランジスタは、降伏電圧に対するオン抵抗の強い依存を示し、縦型DMOSトランジスタのより高いセル密度A/Wは、特に20Vより上の電圧において増大する電圧を有する横型MOSFETよりもよい性能を縦型DMOSトランジスタに与える。
図4Gにおいて示されるショットキーダイオード195は、大きなマイノリティキャリア伝導を示さないが、ショットキーダイオードのダイオードフォワードバイアス特性は、金属層198とN型エピタキシャル層197との間のビルトインバリア電位に大きく依存する。アノード199をセグメントに分割することは、正確な電流の読み出しが、カソード196への電流の一部分においてのみなされるということを約束するものではない。
これらの要求は、本発明に従うカスコード電流センサにおいて達成される。カスコード電流センサは、メインMOSFETと、検知MOSFETとを含む。メインMOSFETは、パワーデバイスを介して計測される電流の経路に接続される。メインMOSFETのソース端子は、検知MOSFETのソース端子に接続される。メインMOSFETおよび検知MOSFETの夫々のゲート端子は共に接続され、ドレイン端子での電圧は、メインMOSFETのドレイン端子での電圧と等しくなるように制御される。典型的には、メインMOSFETのゲート幅は、検知MOSFETのゲート幅よりも係数nだけ大きく、その結果、検知MOSFETにおける電流は、メインMOSFETにおける電流よりも係数nだけ大きい。したがって、本発明のカスコード電流は、検知MOSFETにおいて電流を正確に検出することができるにもかかわらず、メインパワー回路における深刻な電力損失を引き起こさない。
ID1≒(W1/L1)μ・Cox・(VGS−Vt1)・(Vα)
および
ID2≒{W2/(L2±ΔL)}μ・Cox・(VGS−Vt2)・(Vβ±Voffset)
によって近似される。μは、MOSFETのチャネル内での電子の移動度であり、Coxは、ゲートキャパシタンスであり、Vt1およびVt2は、夫々、MOSFET323Aおよび323Bのしきい値電圧であり、L1およびL2は、夫々、MOSFET323Aおよび323Bのチャネル長さである。用語ΔLは、MOSFET323Aおよび323Bのチャネル長さL1およびL2における僅かな差を表わし、デバイス間での電流の不一致を引き起こす。この差は,主に、MOSFET323Aおよび323Bを製造するために用いられるフォトリソグラフィープロセスにおける特別な不均一性に起因する。Voffsetは、MOSFET323Aおよび323Bの夫々に印加されたソース電圧VαおよびVβにおける差を表わす。
ID2/ID1≒1/n
に単純化される。
ID2=gm・(Vα−Vβ±Voffset)≡(ID1/n)±Ioffset
であるようなトランスコンダクタンスgmとを有するトランスコンダクタンスアンプを形成する。
便宜上、電流ソース366および367は、比m≡1となるように同じ構造を有することができ、よって、IsenseおよびID2は、同じ大きさの電流を有し、オフセットがない状況においてIsense=(ID1)/nである。
効果的なオン抵抗RDSに対して
RDS=VDS/ID3=VDS3/ID3+RDS1
この効果的なオン抵抗RDSは、VDSのいかような値に対しても有効である。MOSFET390が大きなゲートバイアスVG3で線形領域においてバイアスされていると、方程式は、
RDS=VDS/ID3=RD3+RDS1
に簡素化され、電流が監視されたMOSFET390の全体的な能力がRDS→0のように向上したことを明らかに示す。NチャネルMOSFET323Aの抵抗は、大きなゲート駆動電圧VG2に対して最小化され、MOSFET323Aを線形領域にせしめ、パワーMOSFET390の状態に関係なく、小さい電圧降下Vαを維持する。
Isense=ID2=(ID1/n)±Ioffset
で与えられるように、これらの全ての不一致を、オフセット電圧または電流として集合的にみなすことができる。
Isense=(ID1/(n±Δn))±Ioffset
となる。Δnは、比nがいずれかのオフセットを補償するように調整される。たとえば、正の電流オフセット+Ioffsetは、Isenseが負荷内を流れる電流ID1を誇張するエラーの結果となる。デバイスのいくつかの部分を遮断することによって、検知MOSFETの幅が「小さく」振舞うように整えることによって、ミラー比は、「n」から大きな値(n+Δn)に増大し、項(ID1/n)は、小さな電流(ID1/(n±Δn))になり、それによって、Isenseの値を正しい値まで下げ、正のIoffset電流によって引き起こされるエラーをキャンセルする。
Wmirror=W2+δ1+δ2+δ3+δ4
の単一のMOSFETとして作動する。
回路1400において、トリミングは、対応するOTPメモリ要素のしきい値を上げることによって、選択されたトリムMOSFET1404A〜1404Dを「オフ」にすることによってのみ達成される。たとえば、MOSFET1404Bをオフにし、Wmirrorを量δ2だけ減少するようにOTPメモリ要素1405Bをプログラムすると、検知MOSFETの有効ゲート幅がW2+δ1+δ3+δ4に低減され、オペアンプ1407のフィードバック制御下において、電流検知出力電流Isenseも減少する。トリム回路1400において、プログラムされていないOTPメモリ要素は、最も高いIsense電流の結果となる。プログラムされた各「ビット」は、ゲート幅W2の割合に応じて検知電流を減少する。全ての「ビット」がプログラムされたときに、検知電流が最小となり、Isense/ID1=1/nである。回路1400は、「ダウンオンリー」トリムアルゴリズムを実現する。トリムMOSFET1404A〜1404Dのゲートは、幅が同じであり、バイナリ重み付けされ、または、所望のタイミングアルゴリズムに依存して変動する幅を有してもよい。
