Abstract

A power DMOS half bridge (R_on=40 mΩ, 30-V operating voltage, 30 A peak current) for windshield-wiper motors is presented. Double speed (DC and 20 kHz PWM output), motor braking, full protection and fault detection functions, and timing sequence (up to 200 ms) are performed by an integrated circuit that integrates the pull-up power transistor as well as the signal circuits on a technology process that allows the integration of bipolar, CMOS, and power DMOS transistors. The power pull-down transistor is a discrete device mounted in the same power package (Multi-watt 11) on an isolated tab
