The AP22919Q is a single-channel load switch with controlled turn-on slew rate. It contains a p-channel MOSFET that can operate over an input voltage range of 1.6V to 5.5V and switch currents up to 1.5A.
The AP22919Q ON state can be controlled by a digital input that is capable of interfacing directly with low-voltage control signals. When power is first applied, a Smart Pulldown is used to keep the ON pin from floating until system sequencing is complete. Once the pin is deliberately driven High (>VIH), the Smart Pulldown will be disconnected to prevent unnecessary power loss.
The AP22919Q is also self-protected, meaning that it protects against short-circuit events on the output of the device. It also has thermal shutdown protection to prevent any damage from overheating.
The AP22919Q is available in a standard SOT363 (Standard) package.
