Monolithic Digital IC
LB11620GP Brushless Motor Driver
Overview
The LB11620GP is a direct PWM drive pre-driver IC that is optimal for three-phase power brushless motors. A motor
driver circuit with the desired output capability (voltage and current) can be implemented by adding discrete transistors or
other power devices to the outputs of this IC. Since the LB11620GP is provided in a miniature package, it is also
appropriate for use with miniature motors as well.
Features
• Three-phase bipolar drive
• Direct PWM drive (input of either a control voltage or a variable-duty PWM signal)
• Built-in forward/reverse switching circuit
• 5V regulator output (VREG pin)
• Built-in current limiter circuit (0.25V (typical) reference voltage)
• Built-in under voltage protection circuit
• Built-in automatic recovery type constraint protection circuit (ON: OFF=1: 18) with protection operating state
discrimination output (RD pin)
• Hall signal pulse outputs

Description
Hall sensor inputs from each motor phase.
The logic high state indicates that IN+ > IN-.
If inputs are provided by a Hall effect sensor IC, the common-mode input range is expanded by biasing either the + or -
input.
Functions as both the PWM oscillator frequency setting pin and the initial reset pulse setting pin. Connect a capacitor
between this pin and ground.
Lock (motor constrained) detection state output. This output is turned on when the motor is turning and off when the lock
protection function detects that the motor has been stopped. This is an open collector output.
Sets the operating time for the lock protection circuit.
Connect a capacitor between this pin and ground. Connect this pin to ground if the lock protection function is not used.
PWM pulse signal input. The output goes to the drive state when this pin is low and to the off state when this pin is high
or open. To use this pin for control, a CTL amplifier input such that the TOC pin voltage goes to the 100% duty state
must be provided.
Forward/reverse control input
Hall signal output (HP output). This provides either a single Hall sensor output or a synthesized 3-sensor output.
Hall signal output (HP output) selection
CTL amplifier + (no inverting) input. The PWMIN pin must be held at the low level to use this input for motor control
5V regulator output (Used as the control circuit power supply. A low-voltage protection circuit is built in.)
Connect a capacitor between this pin and ground for stabilization.
Power supply. Connect a capacitor between this pin and ground to prevent noise and other disturbances from affecting
this IC.
Ground
Output current detection. The current detection resistor (Rf) voltage is sensed by the RF pin to implement current
detection.
The maximum output current is set by RF to be IOUT = 0.25/Rf.
Outputs (PWM outputs).
These are push-pull outputs.
