LB11690 Pre-Driver IC for Brushless Motor Drive in Electric Bicycles

Ordering number : ENN7543 www.DataSheet4U.com 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 conver.

LB11690 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
