TI公司的DRV8305-Q1是三相马达驱动的栅极驱动集成电路,提供三个高精度半桥驱动器,每个可驱动高边和低边N-MOSFET,电荷泵驱动器支持100%占空比,满足汽车应用的AEC-Q100规范,4.4V-45V工作电压,峰值栅极驱动电流1.25A和1A,主要用在三相BLDC和PMSM马达,汽车油泵和水泵,汽车风扇和鼓风机.本文介绍了DRV8305-Q1主要特性,框图,典型应用电路以及汽车两轴电动座椅驱动参考设计TIDA-01330主要特性,框图,电路图,材料清单和PCB设计图.

The DRV8305-Q1 device is a gate driver IC for threephasemotor-drive applications. The device providesthree high-accuracy half-bridge drivers, each capableof driving a high-side and low-side N-channelMOSFET. A charge pump driver supports 100% dutycycle and low-voltage operation for cold cranksituations. The device can tolerate load dumpvoltages up to 45-V.

The DRV8305-Q1 device includes three bidirectionalcurrent-shunt amplifiers for accurate low-side currentmeasurements that support variable gain settings andan adjustable offset reference.

The DRV8305-Q1 device has an integrated voltageregulator to support an MCU or other system powerrequirements. The voltage regulator can be interfaceddirectly with a LIN physical interface to allow lowsystemstandby and sleep currents.
