Designed for pulse width modulated (PWM) control of low-voltage stepper motors as well as single and double DC motors. A3906 is designed for output currents up to 1 A per channel and operating voltages from 2.5 to 9 V.
The A3906 has an internal PWM timer with a fixed off time, the
Sets a peak current based on the selection of a current sense resistor
Resistance. An overcurrent output flag informs the user when the current in the motor winding reaches the peak current determined by the measuring resistor. The fault output has no effect on driver operation.
