TPS2042BDGNR TI Power Distribution | 8-HVSSOP | 2-Ch, 0.5A, 2.7-5.5V

Product Overview

The TPS2042BDGNR 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. It integrates two 70mΩ N-channel MOSFETs with independent enable inputs, providing a compact and efficient solution for power management. The device operates over a wide input voltage range of 2.7V to 5.5V, making it suitable for both 3.3V and 5V systems. Each channel can deliver up to 0.5A of continuous current, with built-in overcurrent and thermal protection to ensure safe operation. The TPS2042BDGNR is available in a space-saving 8-pin HVSSOP package, ideal for space-constrained designs.
