Functional Features

Voltage Monitoring

TLC7703QPWG4 continuously monitors the supply voltage and compares it with the selected threshold voltage. It ensures that the monitored voltage remains within the desired range.

Reset Function

When the monitored voltage falls below the threshold voltage, TLC7703QPWG4 generates a reset signal. This signal can be used to initiate system resets or trigger specific actions in electronic circuits.

Manual Reset

The IC provides a manual reset input (MR) that allows users to manually trigger a reset signal, overriding the automatic monitoring function.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring ensures system stability.
• Low power consumption extends battery life in portable devices.
• Wide operating voltage range makes it compatible with various applications.
