3971 Product details

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.

FEATURES
■ ±2.5 A Load Current Capability per Bridge
■ Parallel Outputs for 5 A Load-Current Capability
■ Low rDS(on) Outputs Typically 325 mΩ source, 175 mΩ sink
■ Synchronous Rectification via Control Logic
■ Internal Undervoltage Monitor
■ Crossover-Current Protection
■ Source Connections for External Current Sensing
■ Thermal Shutdown Circuitry
