Pinout
Here is a brief overview of its pin functions:
1. IN: Power input. Connect to the power supply.
2. OUT: Power output. Connect to the load.
3. GND: Ground.
4. ILIM: Current limit set. Connect a resistor to set the desired current limit.
5. EN: Enable input. Active high; drive high to enable the device.
6. FAULT: Fault indicator. Open-drain output that goes low in case of an overcurrent or overtemperature fault.
7. NC: No connection. Should be left floating or connected to ground.
8. NC: No connection. Should be left floating or connected to ground.
The TPS2557 supports a current range usually from 500 mA to 5 A, adjustable via the ILIM pin, and is designed for applications requiring circuit protection and power distribution.
