Product Overview: MAX809JEUR+T

The MAX809JEUR+T is a compact, highly reliable microprocessor (µP) supervisory circuit produced by Maxim Integrated, a trusted name in the development of innovative analog and mixed-signal products. This precision device is designed to monitor power supplies in µP and digital systems, providing a significant layer of protection against low voltage and other fault conditions that could lead to system failure.

Key Features

• Voltage Monitoring: The MAX809JEUR+T keeps a vigilant watch on the system voltage, ensuring it remains above a preset threshold. If the monitored voltage drops below this level, the device asserts a reset signal to prevent system errors.
• Reset Signal: Upon detection of an out-of-tolerance power supply condition, the device generates a reset signal for a minimum of 140ms after VCC has risen above the reset threshold, ensuring proper system reset.
• Low Power Consumption: This supervisory circuit is optimized for low power consumption, making it suitable for portable and battery-operated applications.
• High Accuracy: The MAX809JEUR+T offers a high degree of accuracy in monitoring voltage levels, with a precision of ±1.5% over the entire temperature range.
• Compact SOT-23 Packaging: The device comes in a small SOT-23 package, which is ideal for space-constrained applications.
