TI公司三个高精度半桥驱动器_TIDA-01330设计图
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.
the gate driver uses automatic handshaking whenswitching to prevent current shoot through. the vdsof both the high-side and low-side mosfets isaccurately sensed to protect the external mosfetsfrom overcurrent conditions. the spi providesdetailed fault reporting, diagnostics, and deviceconfigurations such as gain options for the currentshunt amplifier, individual mosfet overcurrentdetection, and gate-drive slew-rate control.
