BQ24020: TTE connect to GND

Jeff YANG

Part Number: BQ24020

Hi,

We have the pin TTE connected to the ground constantly.

I found in datasheet ,when entry timer fault condition, need toggling TTE to clear the fault, if always connect to GND, may hard to recovery.

Except that, Are there any risks?

Hi Jeff,

BQ24020 does not have TTE, can you confirm which part you are using? Toggling POR (both Vac and Vusb must go below the UVLO threshold - 2.5V), CE, or TTE pins will clear the timer fault.

Best regards,
Nick
