BQ77910A: Windows software for USB Interface Adapter

Bill Dempsey

Part Number: BQ77910A
Other Parts Discussed in Thread: BQ76925

I have a lithium battery that is utilizing a TI BQ77910 cell protector. We have a programming fixture in production that programs the chip's eeprom using the USB Interface Module, shown below. The old module says "2006" and the newer module says "2022" on it. Where can I find the windows software to use this new one?

Thx,

Bill

Hi Bill,

This is the USB2GPIO2, and the 2006 version was the USB2GPIO. These devices have significant differences, and we are currently working to determine compatibility.

Currently, the USB2GPIO is the recommended device, but the firmware loader has been removed from the dedicated website. I am working at this time to track down the removed firmware. I will update this thread will my findings as soon as I can.

Here is a thread with a customer who faced a similar issue: USB2GPIO-LOADER-SW: Cannot find Firmware - Power management forum - Power management - TI E2E support forums.

Best,

Andria

Hi Bill,

I have been unable to locate the USB2GPIO firmware loader. Currently, evaluation using a USB2GPIO or USB2GPIO2 device with the BQ76925 is not possible.

Best,

Andria
