LB11690, 11690H
Pre-Driver IC for Brushless Motor Drive
in Electric Bicycles
Overview
The LB11690 and LB11690H 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.
Functions and Features
• Three-phase bipolar PWM drive (high and low side
n-channel FET drive)
• Maximum supply voltage: 45 V
• Gate drive voltage: about 10 V (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

• In the state where the high side gate is VH and the low side gate is VL, the high side FET
connected to the VH pin will be on and the low side FET connected to the UL pin will also be
on.
• Since the HP output is an open collector output, the high output level is the open state.
