Key Features
- Adjustable Current Limit: The current limit can be set from 100 mA to 1.5 A using an external resistor.
- Overcurrent Protection: The device turns off the switch when the current limit is exceeded and can auto-restart after a fault condition.
- Over-Temperature Protection: Thermal shutdown protection to prevent damage from excessive heating.
- Reverse-Current Protection: Prevents current from flowing when the MOSFET is off and the output voltage is higher than the input voltage.
- Status Flag Output: An active LOW, open-drain output indicates fault conditions such as overcurrent, undervoltage, or overtemperature.
- Simple On/Off Control Interface: The ON pin controls the state of the switch, compatible with low-voltage control signals.
- Compact Package: WLCSP package suitable for space-constrained designs.
Applications
