Product Overview: MAX809LEUR-T from Maxim Integrated

The MAX809LEUR-T is a compact, highly efficient microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. Manufactured by Maxim Integrated, a renowned leader in the industry of analog and mixed-signal engineering, this component ensures that systems operate reliably and within their power specifications.

Key Features

• Voltage Monitoring: The device keeps a vigilant eye on the system voltage, triggering a reset signal if it falls below a preset threshold, which is crucial for preventing microprocessor malfunction due to power instability.
• Reset Output: The reset output is active-low and is guaranteed to remain in the reset condition for a minimum of 140ms after the supply voltage exceeds the reset threshold level. This ensures adequate time for the system to stabilize before the processor starts.
• Low Power Consumption: With a quiescent current of just 17µA, the MAX809LEUR-T is optimized for power-sensitive applications, contributing to overall system efficiency.
• Temperature Range: It operates over a wide temperature range, from -40°C to +85°C, making it suitable for industrial environments and demanding conditions.
• Compact SOT-23 Packaging: The device is available in a small SOT-23 package, which is ideal for space-constrained applications.
