Maxim Integrated MAX6707RKA+T Microprocessor Supervisory Circuit

The Maxim Integrated MAX6707RKA+T is a compact, highly efficient 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 monitoring nominal system voltages from 1.8V to 5V. This supervisory circuit is ideal for use in a wide range of applications, including computers, controllers, intelligent instruments, and portable battery-powered electronics.

This device is offered in a small SOT-23 package, making it an excellent choice for space-constrained applications. The MAX6707RKA+T ensures system integrity by providing several key supervisory functions, including a reset output during power-up, power-down, and brownout conditions. The reset signal remains asserted for a minimum of 140ms after VCC has risen above the reset threshold, ensuring a proper system reset during power-up.

The MAX6707 features an adjustable reset threshold voltage, which allows for flexibility in system design. The threshold can be programmed by the user through external resistors. Additionally, the device includes a manual reset input that enables a reset to be triggered with an external switch or software command, providing an additional layer of system control.

With its low supply current of 5µA (typical), the MAX6707RKA+T is optimized for battery-powered applications, contributing to extended battery life. The device operates over a broad voltage range and is fully specified over the extended temperature range of -40°C to +85°C, ensuring reliable operation in a variety of environmental conditions.
