Working Principles

The TC642BEUA713 is a voltage supervisor IC that continuously monitors the supply voltage. It compares the voltage level with the set threshold voltage and generates a reset signal when the voltage falls below the threshold. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered. The IC operates with low power consumption and provides precise monitoring for reliable system operation.

Detailed Application Field Plans

• Battery-powered devices: The TC642BEUA713 can be used in portable electronic devices, such as smartphones and tablets, to monitor the battery voltage and initiate a reset if the voltage drops too low.
• Industrial control systems: It can be employed in industrial control systems to ensure stable operation by monitoring the power supply voltage and resetting the system if necessary.
• Automotive electronics: The IC can be utilized in automotive applications to monitor critical voltages and provide reset signals to prevent malfunctions.
