... ESD protection ■ Reverse current protection ■ Fault blanking Description The STMPS2242/2252/2262/2272 power distribution switches are intended for applications where heavy capacitive loads and short circuits are likely to be encountered. These devices Ω incorporate 100 m MOSFET high-side power switches for power distribution systems that require multiple power switches in a single package ...

... Overcurrent/over-temperature protection In overcurrent or short-circuit condition, the switch limits the current at 500 mA for STMPS2242/STMPS2252 and 1000 mA for STMPS2262/STMPS2272. If temperature of die goes above limit value, the switch turns OFF. 3.3 Reversed current blocking When the switch is OFF, or when the STMPS device is un-powered (V behaves as an Hi-Z at the output pin, ensuring that no reverse current will flow into the device when Vi< ...
