Monolithic digital IC
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.
