Pinout
Here is a brief overview of the pin functions:
1. IN: Power input pin. Connect this to the source voltage.
2. OUT: Power output pin. This connects to the load.
3. GND: Ground pin. Connect this to the system ground.
4. EN: Enable pin. It activates the device when high.
5. ILIM: Current limit set pin. This pin allows for setting the current limit threshold.
6. FAULT: Fault output pin. An open-drain output that indicates fault conditions such as overcurrent, overtemperature, or undervoltage lockout.
These pins together facilitate the device's function as an efficient power switch, offering protection features such as current limiting, overtemperature protection, and short-circuit protection for safe operation in various applications.
