Description

The MAX809MEUR+T is a voltage supervisor or reset IC designed to monitor power supply levels in electronic circuits. It ensures that microcontrollers and other critical components are reset when the supply voltage drops below a specified threshold. The device operates with a low supply current, making it suitable for battery-powered applications.
Key features include a fixed reset threshold, typically around 2.63V, and a fast reset response time. The MAX809MEUR+T is available in a small SOT23 package, allowing for space-efficient designs. It has a specified operating temperature range of -40°C to +125°C, making it reliable for various environmental conditions.
This component is widely used in embedded systems, automotive applications, and consumer electronics to enhance system reliability by preventing erroneous operation during power fluctuations.

Features

The MAX809MEUR+T is a voltage supervisor and reset IC designed for microprocessor applications. Key features include:
1. Reset Function: It provides a reset output when the supply voltage drops below a specified threshold, ensuring system stability.
2. Voltage Thresholds: Offers various pre-set voltage thresholds (options between 1.58V to 5.0V) for different applications.
3. Active-Low Output: The reset output is active low, which means it is pulled low during a reset condition.
4. Low Power Consumption: It operates with low supply current, enhancing battery life in portable devices.
5. Fast Reset Release: The device ensures a quick reset release when the supply voltage returns to normal.
6. Temperature Range: Designed for operation over a wide temperature range (-40°C to +125°C).
7. Small Package: Available in a compact SOT23 package, suitable for space-constrained designs.
These features make the MAX809MEUR+T ideal for ensuring reliable performance in various electronic systems.
