Microchip MTS2916A双极步进马达驱动方案
Microchip公司的MTS2916A是双极马达驱动器,也能双向控制两个DC马达,两个单独的H桥输出提供电压40V,连续电流750mA,主要用在步进马达,DC马达,汽车HVAC和座位控制.本文介绍了MTS2916A主要特性,框图和应用电路,以及评估板ADM00308主要特性,电路图,材料清单和PCB设计文件.
The MTS2916A motor driver is a CMOS devicecapable of driving both windings of a bipolar steppermotor or bidirectionally control two DC motors. Each ofthe two independent H-bridge outputs is capable ofsustaining 40V and delivering up to 750 mA of
continuous current. The output current level iscontrolled by an internal pulse-width modulation(PWM) circuit that is configured using two logic inputs,a current sense resistor and a selectable referencevoltage. The H-bridge outputs have been optimized toprovide a low output saturation voltage drop.
