... P. GND Power ground Supplementary Explanation • Precautions for Using the AN8267S Observe the following in order to use the AN8267S safely and properly. Operating supply voltage range : 9.6V to 27.6V 1. Maximum applied voltage to the coil output Pins6 and 10 When driving the motor, the counter electromotive power of the coil is applied to the coil output Pins6 and 10 when the output transistor is turned off ...

... Steep Rise Gentle Rise Fig.4 3. AN8267S lock protection When the motor fan is locked, the AN8267S has a function to protect the motor and IC. (lock protection operational prin- ciple) If the motor fan is locked, a sine wave signal is not input from the Hall element any more and the potential of the Pin4 external capacitor increases ...
