What is the difference between TPS2556 and TPS2557?

The TPS2556 features an active-low enable pin, while the TPS2557 features an active-high enable pin.

How is the current limit set?

The current limit is programmed by connecting an external resistor (RILIM) between the ILIM pin and GND.

What happens during an overcurrent event?

The device limits the output current to the programmed threshold and asserts the FAULT pin low after a 9-ms deglitch period.

What is the pinout of TPS2557DRBR?

Use the TPS2557DRBR datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about TPS2557DRBR pinout to locate pins, power rails, and interface signals before layout.
