A3906 Low Voltage Stepper and Single/Dual DC Motor Driver

Designed for pulse-width modulated (PWM) control of low voltage stepper motors, and single and dual DC motors, the A3906 is capable of output currents up to 1 A per channel and operating voltages from 2.5 to 9 V. The A3906 has an internal fixed off-time PWM timer that sets a peak current based on th.
