TPS2231MRGPR TI Power Distribution | 20-QFN (4x4) | 1.5A, 0.5-5.5V

Product Overview

The TPS2231MRGPR from Texas Instruments is a single-channel power-distribution switch designed for applications requiring up to 1.5 A of continuous current. It operates over a wide input voltage range of 0.5 V to 5.5 V, making it suitable for low-voltage systems. The device integrates a 70-mΩ N-channel MOSFET with controlled rise time to minimize inrush current. It features overcurrent protection, thermal shutdown, and under-voltage lockout (UVLO). The enable pin is active high, and the device includes a fault flag output (open-drain) to indicate overcurrent or thermal fault conditions. The TPS2231MRGPR is available in a compact 20-pin QFN (4x4 mm) package, ideal for space-constrained designs.
