Customer want to realize when VBAT drops to 6V
- BAT stop discharge when BAT only
- Or BAT can left Supplement mode and stop discharge even when VBus power < SYS power.
But the problem is they don’t have a Ship FET on board, any SW way to realize it?
I noticed in default charging current setting, VBAT_LOWV can be set to 71.4% * VREG = 0.714 * 8.4V = 6V and this can stop BAT to over discharge. And I think maybe this is a way to solve it.
But the real test, the voltage will still drops to around 5.6V and the IPRECHG is around 10+ mA only while setting to 40mA. Do you have any comments here?
Looking forward to your comments. Thank you!
