Working Principles

The TLC7701QPWRG4Q1 is a voltage supervisor IC that continuously monitors the power supply voltage. It compares the supply voltage with the selected threshold voltage and generates a reset signal when the voltage falls below this threshold. The reset signal remains active until the supply voltage rises above the threshold or a manual reset is triggered through the MR pin. The reset timeout period can be adjusted using an external capacitor connected to the CT pin.

Detailed Application Field Plans

• Automotive electronics: Used in automotive systems to monitor the vehicle's power supply voltage and ensure proper functioning of critical components.
• Industrial control systems: Provides voltage supervision in industrial control panels, preventing malfunctions due to low supply voltage.
• Consumer electronics: Integrated into various consumer devices to protect against voltage fluctuations and ensure reliable operation.
• Medical equipment: Ensures stable power supply in medical devices, preventing potential risks associated with voltage variations.
• Telecommunications: Used in telecom infrastructure to monitor power supply voltage and maintain uninterrupted communication.
