Description
The A3908 is a low voltage bidirectional DC motor driver with a typical input
voltage range of 3 to 5.5 V and output currents up to 500 mA. The unique
output full-bridge incorporates source side linear operation to allow a
constant voltage across the motor coil. This regulated output minimizes motor
voltage change due to I × RDS(on) variation and battery voltage tolerance.
Logic input pins are provided to control the motor direction of rotation,
brake, and standby (< 500 nA supply current) modes and to allow optional PWM
of the sink drivers. Internal protection circuitry includes thermal shutdown,
undervoltage lockout, and crossover current (shoot-through) protection.
The A3908 is supplied in a 2 mm x 2 mm, 0.55 mm nominal height, 8-lead DFN
package, with exposed thermal pad (package suffix EE). This small footprint
package is lead (Pb) free, with 100% matte tin leadframe plating.
Applications include:
▪ Robotic actuators and pumps
▪ Portable printers/scanners
▪ Camera lens/shutter control
▪ Battery powered toys and games
▪ Low noise test instrumentation systems
