Datasheet Summary
MOSFET Driver
The NCP81155 is a high- performance dual MOSFET gate driver in a small 3 mm x 3 mm package, optimized to drive the gates of both high- side and low- side power MOSFETs in a buck or buck- boost application. VCC UVLO ensures the MOSFETs are off when supply voltages are low. A bi- directional Enable pin provides a fault signal to the controller when a UVLO fault is detected.
