2. GND: Ground reference
3. RESET: Active-low reset output
4. MR: Manual reset input

Functional Features

1. Voltage Monitoring: DS1233D-5 continuously monitors the supply voltage and compares it to the preset threshold.
2. System Reset: When the voltage falls below the threshold, the IC generates a reset signal to ensure proper system initialization.
3. Manual Reset: The MR pin allows for manual triggering of the reset function.
4. Power-On Reset: DS1233D-5 provides a power-on reset pulse during system power-up.
5. Debounced Reset Output: The reset output is debounced to prevent false triggering due to voltage fluctuations.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring ensures reliable system operation.
• Small package size enables space-efficient integration.
• Low power consumption extends battery life in portable devices.
• High reliability under various operating conditions.

Disadvantages
