  • BQ25101: charger current when Vsys=3.3V

    Resolved
    Part Number: BQ25101 Hey Expert, when VSYS=3.3V does the charge current will below 20mA? R508=13.5k ohm. so I fast charge=10ma I saw the V lowv=2.4~2.6. on datasheet. so I will say no. when Vsys=3.3 still in fast charge right? Thanks for your support…

    Part Number: BQ25101 Hola, Usamos BQ25101YFPR y encontramos un problema para la siguiente condición. 1. El PCM de la batería está habilitado por un voltaje de batería muy bajo. Sin embargo, el PCM de la batería no se puede…

  • BQ25101: Status of CHG

    TI Thinks Resolved
    Part Number: BQ25101 Hi The customer has a question about the status of CHG, Please help answer. Case 1: Supply the load first, then VIN. During charging, CHG will be low, which is normal. Case 2: Supply VIN first, then load, and during charging, CHG…

  • RE: BQ25101: /CHG keeps low when there is no current

    Hello Hao, Sorry for the delayed response. I was able to see identical behavior in case 2 & 3 with bq25101, using 5V supply on IN and battery simulator at 3.6V on OUT. I altered the TS voltage with potentiometer. Hao Wang14 said: 2. When TS voltage…

  • BQ25101: nCHG pin stays low when there is a small load on the battery

    Part Number: BQ25101 The nCHG behaves as expected when the battery, being charged, is disconnected from the load. However, when the battery is connected to a very small load (> 100uA), the nCHG stays low way beyond the 1.5mA termination current (I have…
