Maxim Integrated MAX809REUR+T Microprocessor Reset Circuit

The MAX809REUR+T from Maxim Integrated is a compact, highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides a significant function by asserting a reset signal to the connected microprocessor whenever the VCC supply voltage drops below a preset threshold, ensuring the proper operation of the system during power-up, power-down, and brown-out conditions.

Key Features

• Precision Monitoring: The device offers precise monitoring of the 3-pin voltage level, ensuring that the connected microprocessor always operates within the safe voltage range.
• Low Power Consumption: With its low power consumption, the MAX809REUR+T is ideal for use in portable and battery-powered applications.
• Manual Reset Input: It includes a manual reset input that allows the user to trigger a reset manually, providing additional system control.
• Reset Timeout: The reset output remains asserted for a preset timeout period after VCC has risen above the reset threshold, ensuring system stability.
• High Accuracy: This component offers high threshold accuracy which is essential for reliable system operation.
• Operating Temperature Range: It is designed to operate over a wide temperature range, making it suitable for a variety of environmental conditions.
