... LB11692JH Overview 1. Output Drive Circuit The LB11692JH uses a direct PWM drive technique. Since the motor speed can be controlled by holding the supply voltage constant and changing the output duty, the power supply design can be simplified compared to designs used with techniques that vary the supply voltage (such as PAM drive). The low side output transistor is switched with a pulse-width modulated signal and the drive output is adjusted by changing the duty ...

... Forward/Reverse Switching The LB11692JH was designed assuming that forward/reverse switching would not be performed while the motor is operating. We recommend that the F/R pin be held fixed at either the low (forward) or high (reverse) level when the motor is turning. Although it will be pulled up to the high level by an internal pull-up resistor (about 40kΩ) when left open, this must be strengthened by an external resistor if fluctuations are large ...
