Hi Experts.

I am looking for Supervisor & Reset ICs with the following features:

Input Power Monitoring: 4.5V
Watchdog Timer
Reset Time Delay
Manual Reset Capability
Watchdog Enable/Disable
I think the TPS35 might be suitable, but it seems that the product is not fully released yet. Please recommend a device that has the features listed above. However, please exclude window watchdog devices from the recommendations.

Thank you.

Hi Jihoon,

What is the voltage threshold for the 4.5V input?

Hi Jesse Villanueva,

Thank you for your quick response.

I would like to provide some additional information about the hardware I am designing.

In the image below, I want to monitor the 5V in the red box and oversee the MCU's operation. The system's power consumption is expected to be around 4A.

The desired features for the Supervisor & Reset ICs are as follows:

Input Power Monitoring
Watchdog Timer
Reset Time Delay
Manual Reset Capability
Watchdog Enable/Disable

Please recommend Supervisor & Reset ICs that meet these conditions.

Thank you, Jihoon.
