Functional Features

Voltage Monitoring

DS1233MS-55+T&R continuously monitors the power supply voltage. It compares the voltage level with the selected threshold voltage and triggers a reset signal if the voltage falls below the threshold.

Reset Function

When the monitored voltage drops below the specified threshold, DS1233MS-55+T&R generates an active-low reset signal. This signal can be used to reset microcontrollers, logic circuits, or other components in the system.

Manual Reset

The MR pin allows for manual resetting of the device. Pulling this pin low will generate a reset signal regardless of the monitored voltage level.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring ensures reliable operation of electronic systems.
• Low power consumption makes it suitable for battery-powered devices.
• Wide operating temperature range enables usage in various environments.

Disadvantages

• Limited threshold voltage options may not cover all application requirements.
• Lack of additional features such as adjustable timeout period.

Working Principles

DS1233MS-55+T&R operates by comparing the power supply voltage with the selected threshold voltage. If the voltage drops below the threshold, it triggers a reset signal. The device continuously monitors the voltage to ensure proper system functionality.
