Other Parts Discussed in Thread: BQ24800, BQ40Z60, BQ24800EVM
Hello fellow engineers,
We are currently redesigning a battery with charger integrated using the BQ40Z50 gauge and BQ24800 charger IC.
Our existing battery uses the BQ40Z60 which can always be waked up by applying a voltage to the charger input (i.e. when cells are inserted the first time, when the chip is in sleep/shutdown).
When connecting the battery cells to the BQ40Z50 EVM for the first time, we noticed the system could only be awoken by pressing the physical WAKE pushbutton. It was not able to wake the system up by applying a charging voltage to the BQ24800.
In the final design, the pack should be able to wake up when the external charger voltage is connected to the BQ24800. How can we implement this?
