Functional Features

• Voltage Monitoring: The MAX16065ETM+CDL can monitor the supply voltage and generate a reset signal when it falls below a programmable threshold.
• Programmable Threshold: The threshold voltage can be programmed to suit different system requirements.
• Reset Timeout: The IC provides a programmable reset timeout period, ensuring that the reset signal is maintained for a specific duration after the voltage returns to an acceptable level.
• Manual Reset: The MR pin allows for manual reset control, overriding the automatic reset functionality.
• Low Power Consumption: With a quiescent current of only 2µA, the MAX16065ETM+CDL minimizes power consumption in battery-powered applications.

Advantages and Disadvantages

Advantages: - Programmable threshold and reset timeout provide flexibility for different system requirements. - Low power consumption extends battery life in portable devices. - Manual reset option allows for manual control in certain scenarios.

Disadvantages: - Limited number of pins may restrict the number of external components that can be connected directly to the IC. - Not suitable for high-voltage applications due to the specified supply voltage range.

Working Principles

The MAX16065ETM+CDL operates by continuously monitoring the supply voltage using an internal voltage reference. When the voltage falls below the programmed threshold, the IC generates a reset signal. This signal remains active for the duration set by the reset timeout period. Once the voltage rises above the threshold and the reset timeout period elapses, the reset signal is deactivated.

Application Field Plans

The MAX16065ETM+CDL is commonly used in various electronic systems where reliable power supply monitoring is critical. Some potential application fields include:

1. Battery-Powered Devices: Portable electronics such as smartphones, tablets, and wearables benefit from the low power consumption and precise voltage monitoring capabilities of this IC.
2. Industrial Control Systems: The MAX16065ETM+CDL ensures stable operation of control systems by providing accurate voltage supervision and reset functionality.
3. Automotive Electronics: In automotive applications, this IC helps monitor and control power supply voltages, enhancing the reliability and safety of electronic systems.
