Abstract

A current sense circuit is provided. The circuit includes a current mirror circuit QN, QN, and diode-connected QP, QP, QP, and QPwith their bases connected together, stacking such that the diode-connected side (QN, QP, QP) aligns and connecting the emitter of QPto the collector of QP. Furthermore, the gates of MPand MPare connected to the collector of QNand QP, respectively. Additionally, the source of MPis connected to the drain of MPvia the source of MPand also connected to the source of a Sense MOS. Moreover, the emitter of QPis connected to the source of MPvia R, and the drain of MPis connected to the source (OUT terminal) of a Main MOS. Furthermore, the gates of MPand MPare connected to the emitters of QNand QN
