TPS2231MRGPT-3 TI Power Distribution | 20-QFN (4x4) | 1.5A, 2.7-5.5V

Product Overview

The TPS2231MRGPT-3 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 2.7 V to 5.5 V, making it suitable for various low-voltage systems. The device integrates a 70-mΩ N-channel MOSFET with a controlled rise time to minimize inrush current, and includes overcurrent, thermal, and reverse-current protection. The enable pin is active high, and the device features a fault output (FAULT) that asserts low during overcurrent or thermal shutdown conditions. Housed in a compact 20-pin QFN (4x4 mm) package, it is ideal for space-constrained designs.
