LB11691H Monolithic digital IC Pre-Driver IC

Ordering number : EN8314 www.DataSheet4U.com LB11691H Overview Monolithic digital IC Pre-Driver IC for Brushless Motor Drive in Electric Bicycles 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.

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
