2. GND: Ground reference
3. MR: Manual reset input
4. RESET: Reset output

Functional Features

• Voltage Monitoring: ADM690AARNZ-REEL continuously monitors the supply voltage and compares it with the preset threshold voltage.
• Reset Signal Generation: When the supply voltage falls below the threshold, the IC generates a reset signal on the RESET pin.
• Manual Reset Input: The MR pin allows for manual reset control, overriding the automatic reset function.
• Adjustable Parameters: Some versions of ADM690AARNZ-REEL offer adjustable threshold voltage and reset timeout period, providing flexibility in different applications.

Advantages and Disadvantages

Advantages

• Reliable Power-On Reset: Ensures proper initialization of microcontrollers and digital circuits.
• Low Power Consumption: Suitable for battery-powered devices.
• Small Package Size: Ideal for space-constrained designs.
• Wide Operating Voltage Range: Compatible with various power supply voltages.

Disadvantages

• Limited Programmability: Some versions may have fixed threshold voltage and reset timeout period, limiting customization options.

Working Principles

ADM690AARNZ-REEL operates by continuously monitoring the supply voltage. When the voltage drops below the preset threshold, it triggers the reset signal generation. This ensures that the connected microcontroller or digital circuitry starts in a known state, preventing unpredictable behavior during power-up or brownout conditions.
