AP2162/AP2172 1A DUAL CHANNEL CURRENT-LIMITED POWER SWITCH Application Note Power Supply Considerations A 0.01-μF to 0.1-μF X7R or X5R ceramic bypass capacitor between IN and GND, close to the device, is recommended. Placing a high-value electrolytic capacitor on the input and output pin(s) is recommended when the output load is heavy. This precaution reduces power-supply transients that may cause ringing on the input. Additionally, bypassing the output with a 0.01-μF to 0.

AP2162/AP2172 1A DUAL CHANNEL CURRENT-LIMITED POWER SWITCH Application Note (Continued) Thermal Protection Thermal protection prevents the IC from damage when heavy-overload or short-circuit faults are present for extended periods of time. The AP2162/AP2172 implements a thermal sensing to monitor the operating junction temperature of the power distribution switch.
