STMPS2141STR Description
STMPS2141STR power distribution switch intended for applications where heavy capacitive loads and short-circuits are likely to be encountered. The STMicroelectronics STMPS2141STR incorporates 90mohm N-channel MOSFET high-side power switches for power distribution. The STMPS2141STR switche 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. 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.
STMPS2141STR Features
12 μA maximum standby supply current
Ambient temperature range from -40°C to 85°C
CMOS and TTL compatible enable input
Undervoltage lockout (UVLO)
8KV ESD protection
Reverse current protection
Fault blanking
500/1000mA continuous current
Thermal and short-circuit protection with overcurrent logic output
Operating range from 2.7V to 5.5V
STMPS2141STR Applications
power distribution
power savings
charge emulation in USB port power applications
load switches
current limit switches
