Frequently Asked Questions
What input voltage range and current-limit behavior does the TPS22942DCKRG4 provide?
The TPS22942DCKRG4 operates over a 1.62 V to 5.5 V input range and includes an internal current limiter that caps output current, protecting downstream loads. When a fault clears, the auto-restart feature automatically re-enables the switch, reducing the need for external supervisory circuitry in portable designs.
How does the auto-restart feature benefit battery-powered IoT sensor designs?
In battery-powered IoT nodes running from 3.3 V or 1.8 V rails, the auto-restart feature of the TPS22942DCKRG4 allows the load switch to recover autonomously after a transient overcurrent event, eliminating the need for a microcontroller intervention and extending battery life by avoiding unnecessary resets or supervisor polling.
What package does the TPS22942DCKRG4 use and what board space does it occupy?
The TPS22942DCKRG4 uses a 5-pin SC-70 (R-PDSO-G5) package with a footprint of approximately 2.0 mm × 2.1 mm, making it one of the smallest load switch footprints available and well-suited for compact wearable and handheld PCB layouts with minimal board area.
When should a designer choose TPS22942DCKRG4 over a simple P-channel MOSFET for load switching?
A designer should choose TPS22942DCKRG4 over a discrete P-channel MOSFET when integrated current limiting, thermal shutdown, and auto-restart protection are needed in a single 5-pin package, since a discrete MOSFET requires external gate drive, current-sense resistor, and comparator circuitry that add BOM count and board area.
