Step2 : Please impress DC15V to VDD and DC5V to VEXT. Step3 : Please perform a voltage setup according to specifications, and impress AC power supply between ACIN1 and ACIN2. Step4 : By inputting signal to the logic part, IPM control is started. (Therefore, please set electric charge to the boot-strap capacitor of high side to turn on low side IGBT before running.) * When turning off the power supply part and the logic part, please carry out in the reverse order to above steps. 11/10/2015 2 www.onsemi.com
