Category: Hardware
Product Number: MAX17703ATG+


       Our customer is using MAX17703 for 8 series Li-Ion Batteries charger, but it can't work:

        Test condition:


         output load: electronic load(CV mode)

         when supply 48V on the MAX17703, no output current, not even 1/10 rated current(precharge current),the flag (FLG2 and FLG1) showing 01(Latched fault or charge suspend due to high- or low-battery-temperature detection*)

       but we check the voltage on Pin16, it was between 1.0V-1.5V.

       will you help to check what problem? appriciate that!!

      below shot is the schematic of MAX17703.
