Pinout
The TPS2553DRVR-1 is a power switch IC from Texas Instruments designed for applications requiring current limiting and protection. It is commonly used in USB power-distribution circuits.
The TPS2553DRVR-1 comes in a 6-pin WSON (DRC) package. Here are the pin functions:
1. IN (Pin 1): This is the input voltage pin. It is connected to the power source.
2. GND (Pin 2): Ground pin for the device.
3. EN (Pin 3): Enable pin. When driven high, the switch is enabled. Driving it low disables the switch.
4. ILIM (Pin 4): Current limit setting pin. Connect a resistor between ILIM and GND to set the desired current limit.
5. OUT (Pin 5): Output voltage pin. This is where the load is connected.
6. OC (Pin 6): Overcurrent flag output. This pin goes low if an overcurrent condition is detected, indicating a fault condition.
These functions support the device's role in providing overcurrent protection and controlled power distribution.
