BQ24232EVM: doesn't charge, battery attachment/removal detection does not behave like in datasheet

Part Number: BQ24232EVM


I'm trying to get BQ24232EVM (completely new board, just arrived) to run but only system path works properly.


EN1=1  EN2=LOW (500mA)
JP1=TMR<->VS (all safety timers disabled)
Battery Voltage = 3,67V
System Load = 330Ohm
TS=0,73V (= within valid window)

The system voltage Vout is correct (4,41V) but I cannot start charging battery. The battery is OK because I can charge it directly from the regulated power supply with V=4,2V. The Vbat remains permanently at 3,67V.

Battery detection/removal sequence works at the first power attachment only. After first battery removal the Vbat voltage slowly rises until 4,56V and remains there; no sequences after that.

Thanks a lot in advance for any support!

kind regards
