FAQ
Please provide a basic application scheme for H-bridge. It is not clear how to
connect it to H-bridge and what are the max permitted voltages.
Please have a look into the below reference how to connect ADuM7234 to an
H-bridge :

Hello,
We are using ADuM3223 to drive DC motor with half bridge and boostrap. The purpose is to replace an old schematic using DC/DC converter with optocouplor.
Mosfet used are IPB027N10N3, the ADuM are managed by gpio on raspberry. We have tested 2 position…
Hi Saviour,
At this time there is only the IBIS model available on the ADuM3223 landing page.
Regards,
Jason
Adum3223 why is the output VOA VOB high when vdd1 = 5V and via VIB = 3.3V? In the specification, when vdd1 = 5V, via VIB needs to be greater than 0.7 * vdd1 = 0.7 * 5V = 3.5V, and the output above 3.5V is high level?
When vdd1 = 5V, is via VIB applicable…
I am using the ADUM3223 with EPC2012C devices switching at 1MHz.
When rising input voltage of the converter leg above around 13V, the high side driver blanks the output for 200us periodically ( period of kHz). Output pulses are down from 5.0 to around…
