Prevent Tiny Cooling Fan coil overheating

In order to prevent "Tiny Cooling Fan" coil overheating or damage, two fans drive contains locked rotor protection off when it detects locked rotor drive output, and the drive will automatically restart after the rotor unlocked. "Tiny Cooling Fan" in internal processing device lock detection Dian shutdown and automatic restart of time, the need for external timing capacitor. AH5772 and AH5773 also integrated overvoltage protection functions such as sound, when it detects an overvoltage condition shut down the device, and then go into standby mode to prevent the motor coil compression. "Tiny Cooling Fan" overtemperature shutdown temperature of the device is effective protection.
