Allegro A3910EEETR-T

驱动器 - 全集成，控制和功率级500mA2.5V ~ 5.5V

Overview

Allegro MicroSystems, LLC announces a new dual half bridge motor driver, designed for low cost, low voltage battery operated applications. This device offers features such as Thermal Shut-down (TSD) and sleep functionality in a small package that is competitive with equivalent discrete circuits. Allegro�s A3910 is targeted at the consumer market with end applications to include game controllers and home entertainment 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 can also be used to drive a single bidirectional DC motor.
