Hello TI:
According datasheet equation,using BQ25856-Q1 EVM Board, RAC1 default 1000K, change RAC2=240K@1%,RAC3=68K@1%, calculate Vacuvp is 4.67V and Vacovp is 23V,but measurement is Vacuvp is 5.5V.
Please tell some reason about it.Thank you!
Hi Pan, Bas on our design calculator as well, this value should be accurate and correct. You can find the design calculator using the link below. Are you sure the resistors are accurate. Even small mismatch can change the voltage. Is the ACOV correct at 23V ? If that is the case, looks like your middle resistor is far off.
