BQ25620EVM: Custom board trips over 10v input , but range is(3.7 to 18)v

Part Number: BQ25620EVM
Other Parts Discussed in Thread: BQ25620

i have designed the custom board according to the sematic(BQ25620EVM) and used the same components but whenever i tried to give more than 10v input the custom board trips and reads only i2c connection but "charge_stat shows not charging" and after that the bq25620 chip not charging the battery anymore even if i reduce the input voltage to 3v-5v.  and when i do the same experiment with evolution board(bq25620) from TI it works fine. so why is it bothering me on custom boards ? i have also checked the connection through multimeter nothing shorted. help me out on that ASAP.
