TPS22945DCKR TI Power Distribution Switches, Load Drivers
The TPS22945 is a single-channel load switch with controlled turn-on and integrated reverse current protection, operating from 1.6 V to 5.5 V and supporting up to 200-mA continuous current . It features ultra-low on-resistance of 100 mΩ typical at 5 V, minimizing voltage drop and power loss. The device includes a slow turn-on feature (100-µs typical) to reduce inrush current and reverse current protection when disabled . Quiescent current is 1 µA typical, with shutdown current of 0.5 µA. The SC-70-5 package enables compact design. Selection is ideal for power domain isolation and power sequencing in space-constrained battery-powered systems. Applications include power gating in smartphones and tablets, battery charging circuit isolation, and load switching in wearable electronics.
