Dear All:

About ADP5090 datasheet page 13 Figure 30. show RE parameter ,My idea is equivalent resistance, have any formula that can be provided to me? This with"VBAT_SD_HYS" "VSYS_PGOOD_HYS" calculation has a relationship. Another this RE Maximum & Minimal impedance value is how much ?thanks

Hi,

RE is equal to the resistance of the parallel resistance of three resistor divides. if the each resistor divide value is same, RE can be 1/3 of each resistor divide value. as long as you can accept the power consumption, you can use much samller resistance but don't recommend to use too bigger value. RE should not bigger than 20Meg.
