ZXMS81045SPQ-13

ZXMS81045SPQ-13 is an IntelliFET high-side power switch. It is a single-channel, high-side, power switch in a SO-8EP (Type E) exposed heatsink package incorporating protective and diagnostic functions. The device comprises a monolithic N-channel vertical power MOSFET with integrated temperature and current sensors, with a charge-pumped gate supply and has a low quiescent current in OFF state. The device is enabled by active high 3.3V and 5V logic level drive to the inputs. The device includes a diagnostic current-sense output proportional to load current and a defined diagnostic fault signal in case of overload operation, overtemperature, short-circuit or open load conditions. Applications include high-side switching with diagnostic feedback for: (12V grounded loads, resistive, inductive, and capacitive loads, suitable for high inrush current loads, incandescent lamps (P27W/P21W), motors, etc), compact low-power replacement for: (relays, fuses, and discrete circuits).
