Working Principles

The MAX6714CUB-T is designed to monitor the supply voltage of a system. It compares the voltage at the TH pin with an internally generated reference voltage. When the supply voltage drops below the programmed threshold, the reset output is asserted, indicating a power failure or low voltage condition. The reset remains active until the supply voltage rises above the threshold and a timeout period elapses.

Application Field Plans

The MAX6714CUB-T can be used in various applications where voltage monitoring and system reset functionality are required. Some potential application fields include:

1. Battery-powered devices: Ensuring proper shutdown or system reset when the battery voltage drops below a certain level.
2. Industrial control systems: Monitoring power supply voltages to prevent damage or data loss during voltage fluctuations.
3. Automotive electronics: Providing reliable reset signals in automotive systems to ensure safe operation and prevent malfunctions.

Alternative Models

• MAX6715CUB-T: Similar features but with a different pin configuration.
• MAX6716CUB-T: Higher supply voltage range and additional features like watchdog timer.
• MAX6717CUB-T: Adjustable threshold voltage with higher precision.
