Avago ACPL-P343 (W343) IGBT栅极驱动方案关键字:工业控制,马达控制, IGBT栅极驱动器;电源管理,开关电源Avago公司的ACPL-P343 (W343)是4A输出的 IGBT栅极驱动光耦合器,集成了一个AlGaAs LED, VCC工作电压15V-30V,工作温度-40℃到105℃,输出电压轨到轨,CMR大于35 kV/us,符合安全标准UL Recognized 3750/5000 VRMS for 1 min., CSA和IEC/EN/DIN EN 60747-5-2 VIORM = 891/1140 Vpeak.主要用在IGBT/MOSFET栅极驱动,AC和无刷DC马达驱动,再生能源逆变器,工业逆变器和开关电源.本文介绍了ACPL-P343/W343主要特性, 功能方框图,两种推荐的应用电路以及ACPL-P34X/W34X评估板主要特性,电路图和PCB元件布局图.ACPL-P343 and ACPL-W343: 4.0 Amp Output Current IGBT Gate Drive Optocoupler with Rail-to-Rail Output Voltage in Stretched SO6The ACPL-P343/W343 contains an AlGaAs LED, which is optically coupled to an integrated circuit with a power output stage. This optocoupler is ideally suited for driving power IGBTs and MOSFETs used in motor control inverter applications. The high operating voltage range of the output stage provides the drive voltages required by gate controlled devices. The voltage and high peak output current supplied by this optocoupler make it ideally suited for direct driving IGBT with ratings up to 1200 V / 200 A. For IGBTs with higher ratings, this optocoupler can be used to drive a discrete power stage which drives the IGBT gate.The ACPL-P343 and ACPL-W343 have the highest insulation voltage of VIORM = 891 Vpeak and VIORM = 1140 Vpeak respectively in the IEC/EN/DIN EN 60747-5-2.ACPL-P343/W343主要特性:4.0 A maximum peak output current3.0 A minimum peak output currentRail-to-rail output voltage200 ns maximum propagation delay100 ns maximum propagation delay differenceLED current input with hysteresis35 kV/us minimum Common Mode Rejection (CMR) at VCM = 1500 VICC = 3.0 mA maximum supply currentUnder Voltage Lock-Out protection (UVLO) with hysteresisWide operating VCC Range: 15 to 30 VIndustrial temperature range: -40℃ to 105℃Safety Approval Pending– UL Recognized 3750/5000 VRMS for 1 min.– CSA– IEC/EN/DIN EN 60747-5-2 VIORM = 891/1140 VpeakACPL-P343/W343应用:IGBT/MOSFET gate driveAC and Brushless DC motor drivesRenewable energy invertersIndustrial invertersSwitchin
