LB11620GP - Brushless Motor Driver
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
Ordering number : ENA1913A 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.
