TI DRV8301 三相马达驱动解决方案关键字:工业控制,马达控制 TI公司的 DRV8301 是用于三相马达的栅极驱动器,包括三个半桥驱动器(每个可驱动两个 N沟 MOSFET), A 沉电流和 源峰值电流,单电源 8V-60V 工作,支持 100% MOSFE T可编程过流保护,主要用在三相无刷 DC马达和永磁同步马达,CPA P和泵,电动自行车,医院病床,轮椅以及电钻, DRV830 1 主要特性,方框图,应用案例电路图以及 DRV8301-HC-C2-KI T评估板主要特性和马达驱动和控制解决方案框图. The DRV8301 isa gate driver IC for three phase motor drive applications. It provides three half bridge drivers, each capable of driving two N-type MOSFETs, one for the high-side and one for the low side. It supports up to sink and source peak current capability and only needs a single power supply with a wide range from 8 to 60V. The DRV8301 uses bootstrap gate drivers with trickle charge circuitry to support 100% duty cycle. The gate driver uses automatic hand shaking when high side FET or low side FET is switching to prevent current shoot through. Vds of FETs is sensed to protect external power stage during overcurrent conditions. The DRV8301 includes two current shunt amplifiers for accurate current measurement. DRV8301 主要特性: Operating Supply Voltage 8V – 60V Sink and Source Gate Drive Current Capability Integrated Dual Shunt Current Amplifiers With Adjustable Gain and Offset Integrated Buck Converter to Support up to External Load Independent Control of3 or6 PWM Inputs Bootstrap Gate Driver With 100% Duty Cycle Support Programmable Dead Time to
