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 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.
