____ Vcc| |GND RST|____|

• Vcc: Power Supply Input
• RST: Reset Output
• GND: Ground

Functional Features

• Monitors the power supply voltage and asserts the reset output when the voltage drops below the specified threshold.
• Provides a debounced reset signal to the microprocessor, ensuring a reliable system startup.
• Offers various reset threshold options to accommodate different voltage requirements.

Advantages

• Low-power consumption, suitable for battery-powered applications.
• Small form factor package allows for space-efficient designs.
• Wide operating voltage range enables compatibility with various systems.
• Debounced reset signal prevents false triggering during power fluctuations.

Disadvantages

Working Principles

The MAX809SEUR+TGA8 operates by continuously monitoring the power supply voltage. When the voltage drops below the specified threshold, the reset output is asserted, indicating a system reset condition. The reset signal remains active until the voltage rises above the threshold and the reset timeout period elapses.

Application Field Plans

The MAX809SEUR+TGA8 is commonly used in various electronic systems where reliable startup and voltage monitoring are critical. Some application fields include:

1. Microcontroller-based Systems: Ensures proper initialization of microcontrollers by monitoring the power supply voltage.
2. Embedded Systems: Provides a reliable reset signal to ensure correct system operation during power-up.
3. Industrial Control Systems: Monitors the power supply voltage to prevent erratic behavior or data corruption.
4. Automotive Electronics: Ensures stable operation of automotive control units by monitoring the power supply voltage.
