ADuM3223 vs ADuM3220

GenevaCooper

Q

We have used ADUM3223 to drive high Voltage output, but it needs two different
supplies (15V). Your colleague at Embedded World 2014 recommended ADuM3220. But
I didn’t find the work voltage of ADuM3320. Could you please tell me, if this

Driving DC motor with ADuM3223 boostrap half bridge

KevinBzh

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.

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?

ADUM3223 blanking high side for 200uS periodically

ZubiSas

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…
