A3916: Dual DMOS Full-Bridge Motor Driver

Description

Top Features

Designed for pulse-width-modulated (PWM) control of lowvoltage stepper motors and single and dual DC motors, the A3916 is capable of output currents up to 1 A per channel and operating voltages from 2.7 to 15 V.

The A3916 has an internal fixed off-time PWM timer that sets a peak current based on the selection of a current sense resistor. An output fault flag is provided that notifies the user of a TSD or overcurrent protection event.

The A3916 is supplied in a low-profile 3 × 3 mm 16-terminal QFN (suffix “ES”) and in a low-profile 4 × 4 mm 20-terminal QFN (suffixes “ES, -1”), both with exposed power tab for enhanced thermal dissipation.

Wide, 2.7 to 15 V input voltage operating range
Dual DMOS full-bridges: drive two DC motors or one stepper motor
Low RDS(ON) outputs
Synchronous rectification for reduced power dissipation
Low-current sleep mode
Overcurrent protection
Internal UVLO and thermal shutdown circuitry
Integrated charge pump
Pin-to-pin compatible with A3906
