FAN8412M/FAN8413M
Application Information
1. Lock Detection & Automatic Restart
FAN8412M/FAN8413M features a lock detection and an automatic restart. The functions can be operated as follows.
When the rotor is locked, there is no change in input signal of hall amplifier.
A capacitor(C

dition or speed information to super IO or system controller. Because the AL or TACO output is open collector type, end user
can pull up this pin with a external resister to the supply voltage of their choice(that is 5 or 3.3V).
