A3916GESTR-T

P1-P3P4-P6P7-P9P10-P11
Designed for pulse-width-modulated (PWM) control of low-
voltage 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 a low-profile 4 × 4 mm 20-terminal
QFN (suffixes “ES, -1”) both with exposed power tabs for
enhanced thermal dissipation.
A3916-DS, Rev. 2
• Wide, 2.7 to 15 V input voltage operating range
• Dual DMOS full-bridges: drive two DC motors or
one stepper motor
• Low R
DS(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
