TPS2074DB TI Power Distribution | 24-SSOP | 4-Channel, 0.5A, 2.7-5.5V

Product Overview

The TPS2074DB from Texas Instruments is a quad-channel power-distribution switch designed for applications requiring multiple independent power rails. It integrates four 0.5A N-channel MOSFET switches with low on-resistance (typically 70mΩ per channel) to minimize voltage drop and power dissipation. 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 features independent enable control, overcurrent protection, thermal shutdown, and under-voltage lockout (UVLO). The TPS2074DB is housed in a compact 24-pin SSOP package, ideal for space-constrained designs.
