TPS2042BDRBT TI Power Switch | 8-SON(3x3) | 2-Ch, 0.5A, 2.7-5.5V

Product Overview

The TPS2042BDRBT from Texas Instruments is a dual-channel, current-limited power-distribution switch designed for applications where heavy capacitive loads and short circuits are likely to be encountered. Each channel provides a continuous load current of up to 0.5A and features a low on-resistance N-channel MOSFET. The device operates over a supply voltage range of 2.7V to 5.5V, making it suitable for both 3.3V and 5V bus-powered applications. The TPS2042BDRBT is available in a compact 8-pin SON (3x3 mm) package, ideal for space-constrained designs.
