A3906 Product details

Description

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 the selection of a current sense resistor. An overcurrent output flag is provided that notifies the user when the current in the motor winding reaches the peak current determined by the sense resistor. The fault output does not affect driver operation.



Features and Benefits

▪ 2.5 to 9 V operation

▪ Internal PWM current limit control

▪ Synchronous rectification for reduced power dissipation

▪ Peak current output flag

▪ Undervoltage lockout

▪ Low RDS(on) outputs

▪ Small package

▪ Brake mode for DC motors

▪ Sleep function

▪ Crossover-current protection

▪ Thermal shutdown
