The TPS2551DBVRG4 from Texas Instruments is a power distribution switch designed for applications requiring robust protection against overcurrent and short-circuit conditions. It incorporates a 94mΩ N-channel MOSFET, offering a typical on-resistance for efficient power delivery.
The current limit is user-adjustable via an external resistor, ranging from 100 mA to 1100 mA, providing flexibility for various load requirements. The device boasts a fast overcurrent response time of typically 2 μS. It operates within a voltage range of 2.5 V to 6.5 V and features reverse input-output voltage protection.
This power switch includes built-in soft-start functionality to minimize inrush current during power-up. The FAULT logic output provides a deglitched report during overcurrent and reverse-voltage events. The TPS2551DBVRG4 is supplied in a compact SOT-23-6 package, suitable for surface mount applications.
Key features include adjustable current limiting, fast overcurrent response, reverse voltage protection, and a low standby supply current of 1 μA maximum. It is designed for applications such as USB ports, cell phones, and laptops where reliable power management is critical.
