Functional Features

Voltage Detection

The S-8211DAJ-M5T1G accurately detects voltage levels within the specified range. It provides a reliable indication of whether the voltage is above or below the selected detection threshold.

Reset Functionality

Upon detecting a voltage level below the set threshold, the S-8211DAJ-M5T1G generates an active low reset signal. This signal can be used to trigger a system reset or perform other necessary actions to ensure proper device operation.

Manual Reset

The manual reset (MR) input allows for immediate resetting of the device, overriding the voltage detection mechanism. This feature is useful in situations where a manual intervention is required.

Advantages and Disadvantages

Advantages

• Wide operating voltage range enables compatibility with various electronic circuits.
• Low quiescent current consumption minimizes power consumption.
