对cm501 RT PMIC VDA短路测试

　　VOUT Short-Circuit Protection （SCP） • The feature prevents potentially uncontrolled inductor current if VOUT is overloaded or shorted to ground • The output is shut down when the fault latch is occurred • Once the fault condition is removed， cycle VIN to clear the fault latch • Over Current Protection （OCP） • To limit the inductor current， the device has a cycle-bycycle current limit • The MOS switch is turned off when OCP is occurred.

　　• VOUT Overvoltage Protection （OVP） • To protect Boost switch in case the feedback is floating or shorted to ground • The MOS switch is turned off when OVP is occurred and the converter continues to operate when VOUT falls below the overvoltage threshold • Thermal Shutdown （OTP） • To prevent damage caused by excessive heat and power dissipation • The device is shut down when OTP is occurred • Once the device cools down， cycle VIN to clear the fault latch
