Hi,
I am working on a project in which we need to drive a 3-phase PMSM. The frequency of the application is 8.138 kHz and the bus voltage is 270Vdc. My colleagues used three Adum5230s to drive the six IGBTs in the inverter. The first prototype had worked…

The ADUM5230 has several undervoltage lockouts. One of these requires VDDB to be at around 12-18v for the lockout to be disabled. I only require the high side of the driver, and so do not need to use VDDB/VOB/GNDB. Does the rest of the chip function …
My aim is to switch a pair of FET's between 90V and 0V. Our requirement is to
switch it and hold the mentioned levels at the output (infinitely). kindly check the circuit
which i designed for the same function.Please confirm whether this arrangement…
HELLO,
I want to use ADUM5230 IN AC inverter for motor driving. Power stage is IGBT FS450R12OE4. QG=3.30uC @VGE=-15V…+15V,Cies=28.0nF,Cres=1.55nF, f=10kHz。
RGint=1.7Ω IC nom = 450A。
My question is : use the buffer configuration in Figure…
I wants to use ADUM5230 with AUIRGB4062D1 in new device (AC 3-phase motor converter, 100...350V in dc power line). Max switching frequency: 20 kHz. Gate capacitance: about 1,5 nF Questions: 1. Can I use ADUM5230 with AUIRGB4062D1 without output buffe…
