STMPS2242MTR

STMPS2242MTR is a power distribution switch intended for applications where heavy capacitive loads and short-circuits are likely to be encountered. These devices incorporate 100mohm MOSFET high-side power switches for power distribution systems that require multiple power switches in a single package. Each switch is controlled by an independent logic enable input. When the output load exceeds the current limit threshold or a short is present, this device limit the output current to a safe level by switching into a constant current mode, pulling the overcurrent (OCx) logic output low. 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 off the switch to prevent damage. Recovery from a thermal shutdown is automatic once the device has cooled sufficiently. Internal circuitry ensures the switch remains off until valid input voltage is present.
