Other Parts Discussed in Thread: TPS65910
Tool/software: Linux
Hello，i have a RTC trouble in AM3359.
I have a custom AM3359 board. But the RTC can not keep the time all the time . When i use a new Li-ion , it can be keep almost 1~2 months,and then the cell has the low voltage(about 2.2V ). Both the same in power off and power on condition,
Our AM3359 mark is AM3359BZCZA80. Silicon Version is PG2.0 And the PMIC is TPS65910. The Li-ion use the Panasonic CR2032. It seems like the RTC have the high consumption or the high leak current.
The attachment file is the schematic of the power part and the RTC part.
Anyone use the on-chip RTC in matured product? Please help me ,thanks ~~
