STMicroelectronics STMPS2151
The STMPS2141, STMPS2151, STMPS2161, STMPS2171 power distribution switches are intended for applications where heavy capacitive loads and short-circuits are likely to be encountered. These devices incorporate 90 mW N-channel MOSFET high-side power switches for power distribution. These switches are controlled by a logic enable input.| Part No. | STMPS2151 |

DESCRIPTION
SOT23-5L SO-8 MSOP8FEATURES
● 90 mW high-side MOSFET switch● 500/1000 mA continuous current
● Thermal and short-circuit protection with overcurrent logic output
● Operating range from 2.7 to 5.5 V 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. Recovery from a thermal shutdown is automatic once the device has cooled sufficiently. Internal circuitry ensures the switch remains off until a valid input voltage is present.
● CMOS and TTL compatible enable input
● Undervoltage lockout (UVLO)
● 12 µA maximum standby supply current
● Ambient temperature range, -40 to 85 °C
● ESD protection: 8 kV HBM
● Reverse current protection
● Fault blanking
● UL recognized components (UL file number: E354278) Table 1.
