LB11691 Description
LB11691 Overview Monolithic digital IC Pre-Driver IC for Brushless Motor Drive in Electric Bicycles The LB11691 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...
