The MAX6466UK from Maxim Integrated is a precision microprocessor (μP) supervisory circuit designed to monitor the voltage levels in digital systems and provide a reliable reset signal to the μP whenever necessary. It is an essential component for enhancing system reliability and robustness by ensuring that the μP resets to a known state during power-up, power-down, or brown-out conditions.

Key Features

• Voltage Monitoring Accuracy: The device boasts a high precision voltage monitoring capability, ensuring that voltage thresholds are detected with accuracy.
• Low Power Consumption: Designed for power-sensitive applications, the MAX6466UK operates with minimal power consumption.
• Manual Reset Input: This feature allows for an external signal to trigger a reset, providing additional control and safety mechanisms.
• Reset Timeout: The device includes an internally fixed delay time for the reset signal, ensuring that the system has sufficient time to stabilize before normal operation resumes.
• Compact SOT23 Packaging: The small size of the SOT23 package makes it ideal for space-constrained applications.

Applications

The MAX6466UK is versatile and can be used in a wide range of applications including portable/battery-powered equipment, computers, controllers, intelligent instruments, and critical μP and μC power monitoring.

Technical Specifications

The device operates over a wide voltage range and has a low quiescent current. It is characterized for operation over the full industrial temperature range (-40°C to +85°C). The output is a push-pull, active-low RESET signal which remains asserted for the reset timeout period after VCC has risen above the reset threshold.

Maxim Integrated's commitment to quality and reliability makes the MAX6466UK a trusted choice for designers looking to secure their system's integrity against power supply anomalies.
