LB11691H
Monolithic digital IC
Pre-Driver IC for Brushless
Motor Drive in Electric Bicycles
Overview
The LB11691H 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

• The condition with the upper gate = VH and the lower gate = UL corresponds to a state in which the upper FET is
turned ON when the VH pin is connected and the lower FET is turned ON when the UL pin is connected.
• The HP output is an open collector output. Therefore, “H” level corresponds to an open state.

This pin is connected internally with the metal in the
bottom of IC. Use both of them in the electrically open
state.
These can be used as wiring because they are not
connected with the internal parts.
