• TH: Threshold voltage selection input

Functional Features

1. Voltage Monitoring: MAX6423US23+ continuously monitors the input voltage and compares it with the threshold voltage set by the TH pin.
2. Reset Signal Generation: When the input voltage falls below the threshold voltage, the RESET pin is activated, generating a reset signal to the connected device.
3. Manual Reset: The MR pin allows for manual reset of the device, overriding the automatic reset function.
4. Adjustable Threshold Voltage: The TH pin provides options to select different threshold voltages according to the specific application requirements.

Advantages and Disadvantages

Advantages

• Low power consumption ensures minimal impact on overall system energy efficiency.
• Wide operating voltage range makes it compatible with various electronic devices.
