Abstract
A motor bridge driver interface, implemented in an ASIC using cost-efficient CMOS technology, is designed to control four external MOS power transistors in a H-bridge configuration for DC-motor driving to achieve accurate and fast switching. Main components of the -interface are comprising a charge pump for generating the control voltage for the high-side N-channel MOS transistors, high-side (HSD) circuits, low-side (LSD) circuits and a complex digital interface for supplying the control signals in a programmable timing scheme. A 'strong' charge pump is used to realize a simple CMOS switch to steer the output to the high-side transistors of said H-bridge. The motor bridge is connected to the battery supply by an additional N-channel MOS transistor to implement a reverse supply protection.
