Dual Half Bridge Motor Driver

The A3910 is a dual half bridge motor driver, designed for low cost, low voltage battery operated power applications. The outputs are rated for operation up to 500 mA.

Direct control of high- and low-side drivers is implemented to allow either high-side or low-side PWM. The motor can be connected to either supply or GND. Using a MOS switch results in improved braking action for the motor, compared to implementation with simple clamp diode.

The A3910 is supplied in a 2 mm × 2 mm 8-contact DFN package (EE) with exposed thermal pad. The package is lead (Pb) free, with 100% matte tin leadframe plating.
