Hi

I using BQ34Z110 for Pb Battery.

EVM using  Current Sens Resister as 10mΩ.

But Our system has Rash Current  for 30A st System Start up.

But  normal operation is about   3 ~ 5A.

Rush Curent only has 30A for short time.

 

【 Question 】

Dose we need change SensResisiter from EVM Resister 10mΩ value  ??

Because of   Vsr range spec is  Min -0.125V ~ Max+0.125V,   but if 30A current  Voltage is 10mΩ x 30A =0.3V.

I worry about device and Resiter Broken with damage by this Rash Current.

Could you tell us ,  Dose we need change Resiter 10mΩ value , or No need Change Value  ???

 Thanks and Regard

Jasper
