Overview

3971 ADVANCE INFORMATION (Subject to change without notice) May 2, 2000 DUAL DMOS FULL-BRIDGE DRIVER Designed to interface between external PWM control logic and inductive loads such as relays, solenoids, dc motors, or stepper motors, each full bridge can operate with output currents to ±2.
5 A and operating voltages to 50 V.
Low rDS(on) DMOS output drivers provide low power dissipation during PWM operation.
Internal charge pump circuitry is used to create a boosted voltage to fully enhance the high-side DMOS switches.
Three TTL-compatible logic-input terminals per bridge allow flexibility in configuring PWM control.
Internal circuit protection includes thermal shutdown with hysteresis, and ...
