Summary:
The Texas Instruments TPS2556DRB is a precision adjustable current-limited power distribution switch designed for applications requiring precise current limiting. It operates over a voltage range of 2.5V to 6.5V.

Description:
The TPS2556DRB from Texas Instruments is a power distribution switch designed for applications demanding precise current limiting and protection against heavy capacitive loads and short circuits. It features an adjustable current limit threshold, programmable via an external resistor, ranging from 500 mA to 5 A typically.

This device operates within a voltage range of 2.5 V to 6.5 V and offers a low on-resistance of 22 mΩ. The switch includes built-in soft-start functionality and a fast overcurrent response time of 3.5 μs. The FAULT logic output asserts low during overcurrent and overtemperature conditions, providing essential fault indication.

Packaged in the DRB package, the TPS2556DRB is suitable for surface mount applications. Its features meet USB current-limiting requirements and it boasts a low standby supply current of 2 μA maximum. The device also offers system-level ESD protection rated at 15 kV / 8 kV.
