STMPS2151STR Datasheet PDF - ST Microelectronics

●The STMPS2151STR is a Power Distribution Switch is intended for applications where heavy capacitive loads and short-circuits are likely to be encountered. This device incorporates 90mR N-channel MOSFET high-side power switches for power distribution. This switch is controlled by a logic enable input. When the output load exceeds the current limit threshold or a short is present, the device limits the output current to a safe level by switching into a constant current mode. When continuous heavy overloads and short-circuits increase the power dissipation in the switch, causing the junction temperature to rise, a thermal protection circuit shuts the switch off to prevent damage.
