TPS2043BD TI Power Distribution | 16-SOIC | 2.7-5.5V, 0.5A per Channel

Product Overview

The TPS2043BD 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 0.5 A and features an integrated N-channel MOSFET with low on-resistance (typically 70 mΩ). The device operates over a wide input voltage range of 2.7 V to 5.5 V, making it suitable for both 3.3-V and 5-V bus-powered applications. The TPS2043BD is available in a 16-pin SOIC package and includes thermal shutdown protection, overcurrent protection, and under-voltage lockout (UVLO).
