BQ79600-Q1: BQ79600-Q1 Reverse Weak Up

Meng Liu

Part Number: BQ79600-Q1

Hi Expert

I found typical bridge without reverse wakeup in SPI Applications circuit and bridge with reverse wakeup in UART in the datasheet.

i want to check can we use SPI with reverse wakeup in the typical bridge?

HI Meng,

Yes, you can use SPI with reverse wakeup in the BQ79600 bridge device.

HI Meng,

Yes, to simply put, it provide the SPI or UART communication choice between the host MCU and BQ79600, it don't have anything to do with the BQ79600 reverse wakeup feature. The INH/BAT connection is what you should pay attention in the datasheet diagram when considering to use reverse wakeup function.

Hope this helps.
