BQ76930: Button on BOOT pin (TS1) of BQ76930

Adam Botka

Part Number: BQ76930

Hi all,

I would have a question regarding on the BOOT-TS1-/DISPLAY:

I want to have a button on TS1 line to wake up the BMS from SHIP to NORMAL mode(at the first boot and after auto ship). I would like to use this button to control the RSOC LEDs too (/DISPLAY). In normally TS1 is used for the MOSFETs temperature, (10K NTC)

It´s ok or can it cause any problem?

Best regards

Adam

Hi Adam,
The switch would have the potential to alter the temperature read by the device if it were on during the time the temperature sample is taken. Temperature is measured every 2 seconds in normal mode. The effect probably depends on how long the user holds the button.
