Electrical Characteristics (@TA = +25° C, VIN = 3.0V to 5.5V, VEN = 0V or VEN = VIN, RFAULT = 10kΩ, unless otherwise specified.)

Thermal protection prevents the IC from damage when the die temperature exceeds safe margins. This mainly occurs when heavy-overload or short-circuit faults are present for extended periods of time. The AP22652/52A and AP22653/53A implement a thermal sensing to monitor the operating junction temperature of the power distribution switch. Once the die temperature rises to approximately +145° C, the thermal protection feature activates as follows: The internal thermal sense circuitry turns the power switch off and the FAULT output is asserted, thus preventing the power switch from damage. Hysteresis in the thermal sense circuit allows the device to cool down by approximately +40° C before the output is turned back on. This built-in thermal hysteresis feature is an excellent feature, as it avoids undesirable oscillations of the thermal protection circuit.

Note: 4. 120μ F output capacitance is a requirement of USB.
