Product Overview: MAX809MEUR+T from Maxim Integrated

The MAX809MEUR+T is a highly efficient, precision microprocessor (µP) supervisory circuit produced by Maxim Integrated, designed to monitor power supplies in digital systems. It provides a significant function in ensuring system reliability by asserting a reset signal whenever the VCC supply voltage drops below a preset threshold, maintaining it active until the supply voltage stabilizes above the threshold. This product is an essential component for managing power-on reset functionality in microcontrollers, microprocessors, and other digital systems, ensuring a proper start-up sequence.

Key Features

• Voltage Monitoring: Accurate monitoring of 3-pin voltages with factory-set thresholds for different applications.
• Reset Output: The active-low RESET output remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level, ensuring system stability.
• Low Power Consumption: With its low supply current of 17µA (typical), it is ideal for power-conscious designs.
• Wide Operating Voltage Range: Designed to operate over a wide voltage range, this device is versatile for various applications.
• Temperature Range: Operates over the extended -40°C to +85°C temperature range, suitable for industrial applications.
