LB11690 Description
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...
