Dear all,
When using the PMIC with no battery connected and supplied form the AC pins with 5V, I see intermittent VSYS dropouts, causing a system reset. The load is about 200mA on the LDO and 100mA on the DCDC, however the drops don't seem related to the load.
The phenomenon is only showing itself when CH_EN and TERM_EN are both enabled in the CHCONFIG0 register.
Any idea what might cause it or how to circumvent this ?
If the charge and termination should not be enabled when the battery is not connected, how to detect the presence of the battery ?
Thank you,
Zoltan
