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.
