Maxim Integrated MAX6707ZKA+T Microprocessor Supervisory Circuit

The MAX6707ZKA+T is a compact, highly precise microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems that require voltage monitoring. This supervisory circuit is ideal for portable and battery-powered equipment due to its low power consumption and small footprint.

This device is designed to assert a reset signal whenever the VCC supply voltage falls below its preset threshold, ensuring that the µP resets cleanly during power-up, power-down, or brown-out conditions. The reset output remains asserted for a preset timeout period after VCC has risen above the reset threshold level, providing a guaranteed reset signal duration.

Key features of the MAX6707ZKA+T include:

• Factory-Trimmed Reset Thresholds: Available in a variety of standard VCC trip points to accommodate common logic levels.
• Low Power Consumption: With a quiescent current of only 1.5µA, it is suitable for battery-powered applications.
• Manual Reset Input: A debounced manual reset input allows for a manual system reset.
• Reset Timeout: Offers a fixed reset timeout period of 140ms (min) to ensure proper system reset.
• Compact SOT23 Packaging: The small 5-pin SOT23 package saves space on PCBs, making it ideal for space-constrained applications.
• Operating Temperature Range: Designed to operate over an extended temperature range from -40°C to +125°C, accommodating industrial applications.

The MAX6707ZKA+T supervisory circuit is also characterized by its versatility, supporting a wide range of supply voltages and catering to different system requirements. The device is available in a tape and reel format (denoted by the +T suffix), which is suitable for automated manufacturing processes, ensuring ease of integration into product designs.

Whether you are designing microprocessor-based systems, embedded controllers, or other sensitive electronic equipment, the MAX6707ZKA+T from Maxim Integrated offers a reliable solution for voltage monitoring and system reset functions, ensuring stable and secure operation of your digital systems.
