Functional Features

• Monitors the supply voltage and generates a reset signal when it falls below the threshold voltage.
• Provides manual reset capability through the MR pin.
• Offers selectable threshold voltage and reset timeout period options.
• Low quiescent current ensures minimal power consumption.

Advantages and Disadvantages

Advantages: - High accuracy in voltage monitoring. - Low power consumption. - Small package size allows for space-efficient designs. - Manual reset capability provides flexibility.

Disadvantages: - Limited threshold voltage and reset timeout period options. - Not suitable for applications requiring higher supply voltages.

Working Principles

The MAX6834IXRD3+T operates by continuously monitoring the supply voltage. When the voltage falls below the selected threshold voltage, the IC generates an active-low reset signal. This signal remains active until the supply voltage rises above the threshold voltage and the reset timeout period elapses.
