ADM809SAKS-REEL7 - Microprocessor Supervisory Circuit

The ADM809SAKS-REEL7 from Analog Devices Inc. is a highly reliable microprocessor supervisory circuit designed to monitor the power supply voltage in microprocessor systems. It provides a precise, factory-trimmed threshold voltage for accurate monitoring, ensuring that your system operates within safe voltage levels at all times.

This compact supervisory circuit is designed to maintain system integrity by asserting a reset signal whenever the V<sub>CC falls below the minimum voltage threshold. The reset signal remains active for a minimum of 140ms after V<sub>CC has risen above the reset threshold level, providing ample time for the microprocessor and other system components to stabilize.

Key features of the ADM809SAKS-REEL7 include:

• Reset Output Stages: The device is available with different options for the reset output stage, including active-high, active-low, and open-drain outputs, catering to a wide range of applications.
• Low Power Consumption: With a low supply current of typically 3.5μA, it is an ideal choice for power-sensitive applications.
• Wide Operating Voltage Range: The circuit operates over a wide voltage range, typically from 1.2V to 5.5V, making it versatile for various microprocessor systems.
• High Accuracy: The reset threshold voltage is factory-trimmed to 4.63V, ensuring high accuracy and reliability in monitoring the power supply.
• Temperature Range: The device operates over the industrial temperature range of -40°C to +85°C, allowing use in harsh environments.

The ADM809SAKS-REEL7 comes in a compact SOT-23 package and is part of a reel, making it suitable for automated assembly processes. It is an excellent choice for managing microprocessor systems in various applications, including portable devices, embedded systems, and industrial equipment.

With its precise voltage monitoring capabilities and low power consumption, the ADM809SAKS-REEL7 from Analog Devices Inc. is a crucial component for any design engineer looking to enhance system reliability and performance.
