Maxim Integrated MAX6707TKA+T Microprocessor Supervisory Circuit

The MAX6707TKA+T from Maxim Integrated is a compact, highly reliable microprocessor (µP) supervisory circuit designed 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 a variety of electronic applications.

This supervisory circuit ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6707TKA+T has a factory-trimmed reset threshold voltage, which means it is pre-configured for a specific application without the need for any external adjustments. This feature simplifies design and enhances product reliability.

The device comes in a small SOT-23 package, making it ideal for space-constrained applications. It is capable of monitoring supply voltages from 1.8V to 5.0V, ensuring versatility across various platforms. The reset output is available in both active-low and active-high configurations, providing design flexibility.

Key features of the MAX6707TKA+T include:

• Factory-trimmed V_CC reset threshold voltage for high accuracy
• 140ms minimum power-on reset pulse width, which guarantees a reliable system reset
• Low supply current of 9µA, making it suitable for battery-powered applications
• Manual reset input, allowing for a system reset via external hardware or software control
• Debounced manual reset input, preventing spurious resets caused by noise or contact bounce
• Immune to short V_CC transients, offering robust performance in noisy environments

The MAX6707TKA+T is ideal for use in a wide range of applications, including microcontroller systems, computers, controllers, intelligent instruments, portable/battery-powered equipment, and set-top boxes. It is designed to increase system reliability and reduce the risk of erroneous operation due to unstable power supplies or unexpected power failures.

With its precision power-supply monitoring, low power consumption, and small form factor, the MAX6707TKA+T from Maxim Integrated is an excellent choice for designers looking to enhance the reliability and performance of their digital systems.
