MAX6705ASKA - Microprocessor Supervisory Circuit

The MAX6705ASKA from Maxim Integrated is a 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 systems that require voltage monitoring.

This compact supervisory circuit is ideal for monitoring 3V, 3.3V, and 5V power supplies in a wide array of applications. It is particularly suitable for portable and battery-powered equipment due to its low power consumption and small size. The MAX6705ASKA comes in a space-saving 8-pin SOT-23 package, making it an excellent choice for systems where space is at a premium.

Key features of the MAX6705ASKA include a precision voltage monitor with a factory-set reset threshold, which ensures that the µP is held in the reset state until the system voltage stabilizes. It also has a manual reset input that allows for a very low supply current of only 1.5µA, making it energy-efficient for battery-operated devices.

The device offers a reset timeout delay, which is factory-set to 280ms, providing the system with enough time to recover after a power failure. The MAX6705ASKA also features an active-low reset output, which remains asserted for the reset timeout period after VCC returns to an in-tolerance condition. This helps to ensure that the µP and other digital components are properly reset.

Maxim Integrated's commitment to quality ensures that the MAX6705ASKA meets the highest standards of reliability and performance. With its robust feature set and compact form factor, this supervisory circuit is an essential component for maintaining system integrity and preventing data corruption due to power supply fluctuations or brownout conditions.
