Pin Configuration

The MAX809TEUR+T10 has three pins:

1. GND: Ground pin
2. RESET: Active-low reset output pin
3. MR: Manual reset input pin

Functional Features

• Voltage Monitoring: The MAX809TEUR+T10 continuously monitors the supply voltage and asserts the reset signal when it falls below the specified threshold.
• Reset Timer: The IC includes an internal timer that ensures the reset signal remains asserted for a specific duration after the voltage rises above the threshold.
• Manual Reset: The manual reset input allows an external signal to force a reset condition, overriding the voltage monitoring function.
• Output Options: The reset output can be configured as either push-pull or open-drain, providing flexibility in connecting to different systems.

Advantages and Disadvantages

Advantages: - Low power consumption - Wide supply voltage range - Multiple reset threshold and timeout options - Small package size

Disadvantages: - Limited number of available reset threshold voltage options - No built-in hysteresis for the reset threshold

Working Principles

The MAX809TEUR+T10 operates by comparing the supply voltage with a reference voltage internally generated. When the supply voltage drops below the specified threshold, the internal comparator triggers the reset signal. The reset signal remains asserted for a specific duration set by the internal timer, even if the supply voltage rises above the threshold during this period.

Detailed Application Field Plans

The MAX809TEUR+T10 is commonly used in various applications where reliable power supply monitoring is critical. Some potential application fields include:

1. Microcontrollers: Ensuring proper system initialization and preventing erratic behavior due to unstable power supply.
2. Industrial Control Systems: Monitoring power supply integrity in control units to prevent data corruption or equipment malfunction.
3. Automotive Electronics: Providing reset functionality to microcontrollers and other critical components in automotive systems.
4. Battery-Powered Devices: Protecting battery life by initiating a shutdown sequence when the battery voltage drops below a safe level.
