The ZXMS82120S14PQ is a dual-channel, high-side power switch in a SO-14EP 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.
