1.Do we have a single device which combined TPS389012+TPS3422?

2.Any simple solution to provided 6 channel reset?.Today customer use 2X SN74ALVC08.Need Vcc=1.8V

  • Eli,

    1. The TPS342x family of push-button controllers are the only devices of their kind in our portfolio. Can you provide more information about how long you would like the button to be pressed before reset occurs? And what you need specifically? A single channel for push-button operation and an additional single channel with voltage monitoring? Does the voltage monitoring require a specific reset delay? Does the push-button reset need to be a certain duration? What is this application for?

    2. For 6 channel reset, I recommend TPS386596 + TPS3780. This solution will work at VDD = 1.8V and has adjustable input thresholds via sense resistors. You can combined the outputs to a single output if desired since all outputs are open-drain topology.

    Please provide feedback on (2) and answer as much as you can for (1). If any of the information is sensitive, please email me directly at
