The TPS2557DRBRG4 from Texas Instruments is a precision adjustable current-limited power distribution switch designed for applications requiring precise current limiting or handling heavy capacitive loads and short circuits. It offers a programmable current-limit threshold adjustable from 500 mA to 5 A via an external resistor.
Key electrical specifications include an operating voltage range of 2.5 V to 6.5 V and a typical on-resistance of 22 mΩ. The device features a fast overcurrent response time of 3.5 µs and a maximum standby supply current of 2 µA. The current limit accuracy is ±6.5% at 4.5 A.
This power switch is housed in a VSON (DRB) package, measuring 3 mm × 3 mm, suitable for surface mount applications. It meets USB current-limiting requirements and includes built-in soft start functionality. The FAULT logic output asserts low during overcurrent and overtemperature conditions, providing system protection.
The operating voltage range is 2.5V to 6.5V.
It is available in a VSON (DRB) package with dimensions 3mm × 3mm (9mm²).
The operating temperature range is -40°C to 125°C.
The adjustable current limit range is 500mA to 5A (typical).
The typical on-resistance is 22mΩ.
The maximum standby supply current is 2µA.
The fast overcurrent response time is 3.5µs (typical).
