Procurement Notes

Verify the specific suffix YTS corresponds to the 14-pin TSSOP tube packaging configuration as documented in official Microchip ordering information. Confirm that the current limit setting matches the external resistor requirements for the target application. Ensure compatibility with the specified 800 mV to 5.5 V input voltage range before integration into the power architecture.

Selection Notes

Select this component when a single-channel high-side switch with integrated overcurrent protection is required. The adjustable current limit allows customization for different load profiles without additional sensing circuitry. Consider the 60 mΩ on-resistance for thermal management calculations. Verify that the 14-pin TSSOP package fits the available PCB footprint constraints.
