Lock Detection Time Setting (automatic recovery mode)
The following formula gives the time, t1, from the point the motor speed is locked until the output is turned off.
t1 [s] = C [
μF] × 4 [V] / 1 [μA]
The output off time, t2, is as follows.
t2 [s] = C [
μF] × 2 [V] / 0.65 [μA]
The time, t3, following the output off state until the motor speed locked state is monitored, is as follows.
t3 [s] = C [
μF] × 2 [V] / 1 [μA]
When pin 4 (LAT) is low (output off latching mode), after the t1 period lock state monitoring, the output is turned off and
the output is held in the off state until either the VCC or VCCM power supply is switched.
