LB11691
Monolithic digital IC
Pre-Driver IC for Brushless
Motor Drive in Electric Bicycles
Overview
The LB11691 are three-phase bipolar PWM drive pre-driver ICs that allow the output circuits to be implemented using
only n-channel FETs. These ICs can implement, at low cost, high-efficiency drive circuits in applications that use motors
that require high drive currents. These ICs include a built-in Hall sensor signal F/V conversion circuit and can provide a
voltage that is proportional to motor speed for use, for example, in speedometers for electric bicycles. These ICs also
support use in applications that holds the speed controlled at a constant rate as the load varies.
Features
Three-phase bipolar PWM drive (high and low side n-channel FET drive)
Maximum supply voltage : 45V
Gate drive voltage : about 10V (high and low side n-channel FETs)
Hall sensor signal F/V conversion circuit (one-shot multivibrator output)
Synthesized three-phase Hall sensor signal output
Built-in current limiter and undervoltage protection circuits
