Part Number: TCA6408A

Hi Team,

I have question about TCA6408A.

We find high current occur when ADDR pull VCC.   Output PIN always high.

When ADDR pull GND. current just 10mA? Right?

May I know how to let TAC6408 into standby mode? since our power source is Battery.

    Hi Cao Cao,

    I would not expect much difference in current consumption between pulling ADDR high or low. How much current are you observing? Are you able to communicate with the device and reconfigure P[7:0] under both conditions?

    This device will be in a low-current standby state when SCL is not toggling. Under this condition, the current consumption is typically just 1 uA.

    Regards,
