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 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.
The A3906 is provided in a 20-contact, 4 mm × 4 mm, 0.75 mm nominal overall height QFN, with exposed pad for enhanced thermal dissipation. It is lead (Pb) free, with 100% matte tin leadframe plating.
Applications include the following:
▪ Digital still cameras (DSC)
▪ Cell phone cameras
▪ USB powered devices
▪ Battery powered devices
▪ 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
