TPS2044D TI Power Distribution Switch | 16-SOIC | 4-Channel, 0.5A, 2.7-5.5V

Product Overview

The TPS2044D from Texas Instruments is a quad-channel power-distribution switch designed for applications requiring multiple independent power rails. Each channel provides up to 0.5A continuous current with a typical on-resistance of 70mΩ. 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. Integrated over-current and thermal protection ensure robust operation in fault conditions. The TPS2044D is available in a compact 16-pin SOIC package, ideal for space-constrained designs.
