STMicroelectronics STMPS2242
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 incorporate 100 mΩ MOSFET high-side power switches for power distribution systems that require multiple power switches in a single package. When the output load exceeds the current limit threshold or a short is present, these devices limit the output current to a safe level by switching into a constant current mode, pulling the overcurrent (OCx) logic output low.| Part No. | STMPS2242 |

DESCRIPTION
SO-8 MSOP8 Each switch is controlled by an independent logic enable input. 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. Table 1.
