Product Overview: ADM809MART-REEL7

The ADM809MART-REEL7 is a highly reliable, precision microprocessor supervisory circuit from Analog Devices Inc., designed to monitor power supplies in digital systems. It provides a significant level of system integrity by resetting the microprocessor during power-up, power-down, and brown-out conditions. The compact and efficient design makes it an ideal choice for portable and space-constrained applications.

Key Features

• Voltage Monitoring: This device actively monitors the supply voltage of 3.08V, ensuring that the connected microprocessor or digital system operates within the acceptable power range.
• Reset Output: The ADM809MART-REEL7 features an active-low reset output, which is asserted when the supply voltage drops below the factory-set reset threshold. The reset output remains asserted for a minimum of 140ms after V<sub>CC has risen above the reset threshold, providing a stable reset signal for the microprocessor.
• Low Power Consumption: With its low power consumption, this supervisory circuit is suitable for battery-powered equipment, helping to extend the operational life of the product.
• High Accuracy: The reset threshold accuracy is ±2.5%, which ensures reliable operation without false triggering or unnecessary resets.
• Temperature Range: The device is operational over the industrial temperature range of -40°C to +85°C, making it versatile for various industrial applications.
• Packaging: The ADM809MART-REEL7 comes in a compact SOT-23 package and is available in tape and reel form, facilitating efficient assembly processes for high-volume production.
