Pinout

The TPS22961DNYR is a load switch from Texas Instruments with a pin count of 6. Its primary function is to control the power delivery to a load by providing an on/off switch capability for power paths.
The pin functions are as follows:
1. IN (Pin 1): Power input.
2. SW (Pin 2): Switch output connected to the load.
3. GND (Pin 3): Ground reference.
4. ON (Pin 4): Control input to enable or disable the switch; active high.
5. FLT (Pin 5): Fault indicator output; signals over-current or thermal shutdown events.
6. NC (Pin 6): No connect, should not be connected to anything.
The TPS22961 is designed for applications requiring controlled power management, allowing for efficient power distribution with minimal voltage drop and reduced power loss.
