ADM809MARTZ-REEL Microprocessor Supervisory Circuit by Analog Devices Inc.

The ADM809MARTZ-REEL from Analog Devices Inc. is a state-of-the-art microprocessor supervisory circuit that provides a compact, efficient, and reliable solution for monitoring power supplies in microprocessor systems. This device enhances system integrity by ensuring that the microprocessor is reset to a known state during power-up, power-down, or if a brown-out condition occurs.

Designed to maintain system stability, the ADM809MARTZ-REEL operates by monitoring the supply voltage of a microprocessor and automatically asserting a reset signal whenever the supply voltage drops below a preset threshold. This reset signal remains asserted until the supply voltage returns to an acceptable level and remains stable for a specified period, known as the reset timeout period. This feature is critical for preventing the microprocessor from executing code erroneously due to insufficient supply voltage.

The ADM809MARTZ-REEL is available in a compact SOT-23 package, making it an ideal choice for space-constrained applications. The device is part of the ADM809 series and is provided in tape and reel form, denoted by the "-REEL" suffix, suitable for automated manufacturing processes.

Key features of the ADM809MARTZ-REEL include:

• Power supply monitoring at a fixed threshold voltage
• Low power consumption suitable for battery-operated systems
• Reset timeout period to ensure system stability
• Push-pull active-low reset output
• Wide operating temperature range suitable for various environments
• Guaranteed reset valid to VCC = 1.0 V for low voltage operations

The device is ideal for portable electronics, computers, controllers, and other microprocessor-based systems that require precise and reliable monitoring of the power supply to maintain proper operation. With its robust design and built-in features, the ADM809MARTZ-REEL ensures that electronic systems are consistently operating safely and effectively, minimizing the risk of data loss or damage due to power supply issues.

By integrating the ADM809MARTZ-REEL into your design, you can trust that Analog Devices Inc. has provided a high-quality component that aligns with the industry's best practices for power supply management and microprocessor supervision.
