MM912 H634: value of minimum Vsense input current

massimilianodes — Mon, 11 Feb 2019 16:56:44 GMT

Hello we would like to know the value of the minimum current at the Vsense input ( Pin 18 ) of this device

we think that in the circuit there is a voltage divider ( 750 kohm ? ) and some ESD protection components connected to the input,

but we do not find any detail on the min /max current that this input adsorbs at min. and max temperature.

pl. consider that in our application, this pin is connected by a 10K series resistor ( acc. to datasheet requirements ) to a 10 V battery.

and please consider that, for an issue we have at board level, we would like to possibly increase this current!

so, if the divider is a fixed divider, could be usefull for us to know:

1) how much we could increase the current using a reduced external serial resistor, ( for example a 5K instead of the 10K value recalled by datasheet) and,

2) how can we calibrate the micro at our EOL, to compensate for a reduced voltage drop across the external series resistor
