2. About the switch time from the stand-by state to the state of operation
Application Circuit Example
1. Example of applied circuit when two DC motor driving
When IN1, IN2, IN3, IN4 are "L", this IC has completely stopped operating. After the time of reset of about 4μs of an
internal setting, it shifts to a prescribed output status corresponding to the state of the input when the signal enters the
input terminal.
Reset of about 4μs doesn't hang even if the motor is driven from the stand-by state when either CH drives and the
output becomes an output status corresponding to the state of the input. As for full power TR between the reset time,
turning off is maintained.
