TCA6408A-Q1: Max supply volatge

Amber Si

Part Number: TCA6408A-Q1

Hi team,

I want to check TCA6408A-Q1 support 1.8/ 2.5/ 3.3V I2C, but don't support 5V I2C?

Regard,

Amber

As shown in the absolute maximum ratings, voltages of 5 V can damage the device.

Hi Ladisch,

Do we have I2C expansion device supports 5v I2C with 8ch in Auto BMS ? Thanks.

Hey Amber,

You may take a look at the TCA9539-Q1 that will be able to support inputs up to 5V:
