I have designed a battery charging circuit for a lithium ion battery.When i connect a battery the charging IC seems to do nothing. Only when i use a multimeter probe to measure the drop across VFB pin i.e R16 the IC starts to charge,voltage on this pin slowly climbs up to 3.3V like it should. without the meters measurement the IC does not charge the battery.All the components have been checked and is soldered properly. can someone explain what's going on. sorry, i haven't updated schematic .Actual resistor i have used achieves 12.8 float voltage. R15 is 976K, R16 is 340K when i measured across R16 the voltage was 3.22 with battery voltage being 12.6 and it kept increasing towards 3.3 the battery float voltage approaching 12.8, but when i remove the multimeters probe from R16 it stops charging
