Allegro A3910EEETR Dual Half Bridge Motor Driver Designed For Low-Cost Low-Voltage Applications

Shenzhen Mingjiada Electronics Co., Ltd. supplies Allegro A3910EEETR dual half-bridge motor driver.Designed for low-cost, low-voltage battery-powered applications, the A3910EEETR is quickly becoming a popular choice for consumer electronics and industrial applications due to its small package, high efficiency performance, and rich protection features.

Product Description Of A3910EEETR

A3910EEETR 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.

A3910EEETR 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 A3910EEETR 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
