Hi , I would like to know the what time about Alert trigger ?
As i checked with datasheet below , I concern the response time. I hope it will small then 20us
If it can be meet 20us? How fast it is ADM1293 can ?
The input monitoring on the ADM1293 is achieved by ADC rather than comparator.
An internal ADC is monitoring current and up to two voltages in a round-robin fashion. The reaction time is limited by ADC conversion rate and the internal averaging setting.
The ADM1293 can not guarantee the VAUX warning reaction time to be lower than 20us.
It can be achieved by an comparator like ADCMP354.
