Other Parts Discussed in Thread: BQ40Z50
Hi,
We are working on a battery product which will have the BQ4050 as its BMS.
The product shall also have a companion MCU which is to monitor the battery whenever it is in charge or discharge state.
I understand that I can use the LED signals to wake up the MCU when it is in charge state.
However I can find no information on how I can wake up the MCU when the battery is being discharged without repeatedly polling the BMS through communications.
Therefore is there a method/signal which can be used to wakeup the MCU from a sleep signal if the BMS is discharging current?
Similarly does the BQ4050 have a signal to indicate that the BQ4050 is in shutdown mode? Can the BTP_INT signal be used for this purpose?
Thanks and regards,
Andre Cilia
