Product Overview
The TPS2048DR from Texas Instruments is a dual-channel, current-limited power-distribution switch designed for applications requiring precision power management. It operates over a wide input voltage range of 2.7V to 5.5V and provides up to 0.5A of continuous current per channel. The device features a low on-resistance (70mΩ typical) to minimize power loss and heat dissipation. It includes overcurrent, overtemperature, and reverse-current protection, making it ideal for USB ports, hot-swap supplies, and other power-distribution systems. The TPS2048DR is available in a compact 16-SOIC package, suitable for space-constrained designs.
