The first thing I need to confirm is that I'm considering a charging circuit for a 7-cell NiMH rechargeable battery with BQ25171EVM.
If I don't use TS, can I pull down TS with 10kΩ?
(Currently, when I pull down the TS with 10kΩ, the charging circuit doesn't work properly.
(Currently, when TS is pulled down at 10kΩ, the charging circuit does not work properly and both STAT1 and STAT2 are not lit.
Secondly, I'm considering a charging circuit for a 7-cell NiMH rechargeable battery with BQ25171EVM.
The TS is not used, but I am trying to keep the TS within the hot and cold thresholds described in the datasheet.
Please tell me the possible reasons.
If the voltage is below 1.05V, it will drop to LOW after startup.
When the voltage is above 1.06V, the voltage stays HIGH but the LED of STAT1 lights up.
The voltage is above 1.06V and stays HIGH, but the LED on STAT1 lights up and the charging does not start.
