TCA9548A: Hardware reset / power-cycle of I2C devices connected to TCA9548A

Part Number: TCA9548A
Other Parts Discussed in Thread: LDC1614

Hello,

I would like to reset / power-cycle several I2C devices (LDC1614) connected to TCA9548A channels, in case of a rare,
otherwise unrecoverable IC2 bus problem.

My hardware-setup:

- TCA9548A powered by a DC-DC converter out 5VDC, together with I2C master.

- TCA9548A secondary side pull-ups powered by a DC-DC converter 3.3VDC.

The latter DC-DC converter is also powering all LDC1614 devices on the board. It has an enable input connect
to MCU board (running from the 5VDC power supply)

Though the provision is there to power-cycle (reset) all I2C devices, meanwhile I have some doubts if it is really save to do so.
After all, during such reset action the TCA9548A would be still powered-on, but the pull-up on the mux channels would see 0VDC
because the 3.3VDC converter would be disabled for short period of time.

Regards,

Jo
