dear TI guys,
my customer use bq24072 occur the following issue:
follow the typical application of the datasheet,my customer design a circuit board,when the vin =5v,the EN2=high,EN1=low,the Iin current is about 20mA, the device seems not to work。
i check the OVP,UVLO and output limited current,they are all ok。but when i test the voltage of the TS pin by the multimeter ,the device begin to charge ,when i take away the probe,the device return the befor status(cant charge)。the application schematic as below ,
can you tell me why occur such case and how should i resolve the issue?
