The MAX809SEUR+ from Maxim Integrated is a compact, highly-reliable microprocessor (µP) supervisory circuit, designed to monitor power supplies in µP and digital systems. It provides a significant function by asserting a reset signal to the µP during power-up, power-down, and brown-out conditions, ensuring that the µP starts up in a known state every time.

Key Features

• Precision Monitoring: This device features a precision voltage monitor with a factory-set reset threshold voltage, ensuring accurate monitoring of the system voltage.
• Low Power Consumption: With its low supply current draw of only 20µA (typical), the MAX809SEUR+ is an ideal choice for power-sensitive applications.
• Manual Reset Capability: An additional manual reset input allows for a manual override, providing flexibility in system control and recovery.
• Reset Timeout: It offers a 140ms (min) reset timeout period, which guarantees the system has sufficient time to stabilize before it becomes operational again.
• Operating Temperature Range: The device is designed to operate over a wide temperature range from -40°C to +105°C, making it suitable for various environments and applications.
