Maxim Integrated MAX6306EUK31D3+T - Microprocessor Reset Circuit

The MAX6306EUK31D3+T is a versatile and reliable microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems that require precision voltage monitoring.

This device is particularly well-suited for portable and compact electronics due to its small SOT-23 package. It ensures that the µP and its peripherals are reset properly during power-up, power-down, and brown-out conditions. The reset output remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level, ensuring that the system has ample time to stabilize before the processor starts executing code.

The MAX6306EUK31D3+T offers a factory-set reset threshold voltage of 3.1V, making it suitable for use with 3.3V power supplies. Its low supply current of 1.5µA (typical) is particularly beneficial for battery-powered applications where power conservation is critical.

Key features of the MAX6306EUK31D3+T include:

• Factory-Set Reset Threshold Voltage: 3.1V
• Minimum Reset Timeout Period: 140ms
• Immune to Short VCC Transients
• Low Supply Current: 1.5µA (typ.)
• Wide Operating Temperature Range: -40°C to +85°C
• Compact SOT-23 Packaging

This device is ideal for applications that require high reliability and extended battery life, such as portable/battery-powered equipment, computers, controllers, intelligent instruments, and critical µP power monitoring. The MAX6306EUK31D3+T's ability to automatically reset a µP without manual intervention enhances system safety and performance, making it a smart choice for designers looking to improve the robustness of their digital systems.

Maxim Integrated's commitment to quality ensures that the MAX6306EUK31D3+T microprocessor supervisory circuit is a reliable component for maintaining system integrity through varied and challenging power conditions.
