Product Overview: MAX6366PKA46+T from Maxim Integrated

The MAX6366PKA46+T is a highly robust, low-power microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides a significant level of system reliability through its ability to reset a µP during power-up, power-down, and brown-out conditions. The device comes in a compact 8-pin SOT23 package, making it ideal for space-constrained applications.

This supervisory circuit is particularly suitable for battery-powered equipment due to its low power consumption. With a supply voltage range from 1.2V to 5.5V, the MAX6366PKA46+T can cater to various applications, ensuring that the µP's power supply remains within acceptable limits. It boasts a factory-trimmed reset threshold voltage set at 4.63V, which is specifically designed to monitor 5V power supplies.

One of the key features of the MAX6366PKA46+T is its manual reset input, which allows for a very low standby current. This manual reset can be activated with a push-button to initiate a system reset, providing an additional layer of control for system maintenance and troubleshooting. The device also offers a reset timeout period of 140ms (min), ensuring that the µP has adequate time to initialize after a reset signal has been issued.

The MAX6366PKA46+T includes an active-low reset output, which remains asserted for the reset timeout period after V_CC has risen above the reset threshold. This active-low reset signal ensures compatibility with most µP and digital logic interfaces. Furthermore, the device is capable of operating over the extended temperature range of -40°C to +125°C, making it versatile for use in various environmental conditions.

Maxim Integrated's commitment to quality and reliability is evident in the MAX6366PKA46+T supervisory circuit. It is designed to enhance system stability and prevent data corruption during adverse power conditions, making it an essential component for any mission-critical application where consistent performance and uptime are paramount.

Whether used in portable devices, computers, controllers, or other digital systems, the MAX6366PKA46+T offers a compact, efficient, and reliable solution for power supply monitoring and µP supervision.
