TPS22943DCKR – TEXAS INSTRUMENTS

The TPS22943DCKR is a compact load switch with ultra-low ON-resistance (typically 33 mΩ) and integrated slew rate control, designed to manage power distribution in space-constrained systems. Operating from 1.1V to 3.6V input voltage, it supports loads up to 1.5A, making it suitable for mobile devices, wearables, and embedded systems. The device features a controlled turn-on mechanism to limit inrush current, protecting sensitive downstream components. Its low shutdown current (less than 1 μA) is ideal for battery-powered applications where energy efficiency is critical. A built-in quick output discharge circuit ensures a defined OFF state for capacitive loads. The device is enabled via a logic-level control pin, compatible with standard GPIOs. Packaged in a tiny SC70-6 (DCK) form factor, the TPS22943DCKR fits easily into high-density PCBs. Engineers appreciate its combination of low R_DS(ON), fast response, and protection features in applications such as SoC power rail switching, USB port control, and load sequencing. Its ease of use and minimal external components make it a reliable choice for low-voltage system design.
