The LB11693JH is a three-phase brushless motor driver IC that uses a direct PWM drive technique to achieve highly
efficient drive. It is optimal for driving fuel pump motors and other miniature motors.
• Soft phase switching + Direct PWM drive
• PWM control based on both a DC voltage input (the CTL voltage) and a pulse input
• Provides a 5V regulator output
• One Hall-effect sensor FG output
• Built-in integrating amplifier
• Automatic recovery constraint protection circuit (on/off = 1/14), RD output
• Built-in current limiter circuit
• Built-in LVSD circuit
• Built-in thermal protection circuit

... Power Supply Stabilization Since the LB11693JH uses a control method based on PWM switching, the power supply lines are susceptible to disruption. Electrolytic capacitors with an adequate capacitance for stabilization must be connected between V CC and ground. If diodes are inserted in the power supply lines to prevent destruction of the equipment if the power supply is connected in reverse, the power supply lines will be particularly susceptible to disruption ...

... Forward/Reverse Switching The LB11693JH 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 ...
