Dual 4A load switch with 27 mOhm Rds(on) for multi-rail power sequencing
The TPS22968NDPUR is a dual-channel N-channel load switch from Texas Instruments, each channel rated for 4 A continuous output with a typical on-resistance of 27 mOhm. That Rds(on) figure means conduction loss stays under 110 mW per channel at full load — a meaningful margin when routing 4 A through a 14-WSON package without a heatsink. The load voltage range spans 0.8 V to 5.5 V, covering sub-1V core rails for modern SoCs up to legacy 5V peripheral buses. The device is slew-rate controlled, so each channel ramps up gradually to limit inrush current and prevent supply droop on hot-plug or power-up events.
Industrial temperature grade and 14-WSON package for space-constrained boards
No external Vcc supply is needed — the switch is self-powered from the load voltage, simplifying the BOM by eliminating a separate bias rail. The On/Off interface is non-inverting, so a logic high on the enable pin turns the channel on.
