Part Number: BQ25798 Tool/software: Hi,
Just wanted to know for a single cell configuration, if the input voltage to the BQ2598 is 20V, will we get 5V (or near by) at the output i.e SYS pin?
Will the buck operation happen internally?
Part Number: BQ25798 I'm trying to read the battery ADC value using the bq25798.
According to the datasheet, I need to enable the 7-bit ADC_EN register in REG2E.
1. REG2E_ADC_Control Register (Offset = 2Eh) [reset = 30h] -> 8-bit data
The current…
Part Number: BQ25798 We are implementing the BQ25798 in a power-management solution and would like to add a mechanical ON/OFF toggle switch to fully turn the system on or off. However, after reviewing the datasheet and available application notes, we…

Part Number: BQ25798 Tool/software: Hi jeff,
Here I see an issue when I connect power for charging even though battery is low the voltage read from the register is 4v,
But actually the battery will be 3.6v
How do I take exact battery voltage when…
