[原创] Microchip MIC4609 600V三相MOFET－IGBT驱动方案

Microchip公司的MIC4609是600V三相MOFET/IGBT驱动器,栅极驱动电压高达20V,带可编重起延迟的过流保护,1A栅极驱动器,输入滤波器时间300ns,结温-40℃到+125℃,主要用在3相马达驱动,现场控制(FOC),白色家电,无刷直流风扇.本文介绍了MIC4609主要特性,功能框图和应用电路,以及MIC4609马达驱动评估板主要特性,电路图,材料清单和PCB设计图.

The MIC4609 features a 300 ns typical input filteringtime to prevent unwanted pulses and a 550 ns ofpropagation delay.The MIC4609 has TTL inputthresholds.The robust operation of the MIC4609 ensures that theoutputs are not affected by supply glitches, High Side(HS) ringing below ground,or HS slewing withhigh-speed voltage transitions.Undervoltageprotection is provided on both the low-side andhigh-side drivers.

The MIC4609 is available in a 28-pin wide SOICpackage.The MIC4609 has an operating junctiontemperature range of -40℃ to +125℃.

MIC4609主要特性:

• Gate Drive Supply Voltage up to 20V
• Overcurrent Protection with ProgrammableRestart Delay
• 1A Gate Drivers
• Dual (HI/LI) Inputs per Phase
• Fault Signal Asserts on Overcurrent andVDD UVLO
• TTL Input Thresholds
