Maxim Integrated MAX6336US20D3 Microprocessor Supervisory Circuit

The MAX6336US20D3 is a highly reliable microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated, a leader in analog and mixed-signal engineering. This device is specifically engineered to monitor power supplies in µP and digital systems, providing excellent circuit reliability and low cost by eliminating external components and adjustments when used in system monitoring applications.

Featuring a precision voltage monitor, the MAX6336US20D3 keeps a vigilant watch over the power supply voltage levels of µP and digital systems. It ensures that the system operates at optimal levels by generating a reset signal whenever the VCC supply voltage falls below a preset threshold. The reset output remains asserted for a minimum timeout period after VCC has risen above the reset threshold, providing a guaranteed reset duration and allowing the power supply and processor to stabilize before resuming operation.

The device operates with a nominal threshold voltage of 2.0V, making it suitable for low-voltage operations. It has an integrated watchdog timer that can be disabled if not required, providing additional flexibility. The MAX6336US20D3 offers an active-low, push-pull reset output, which ensures compatibility with a wide range of microprocessors and digital systems.

Designed in a compact SOT-143 package, the MAX6336US20D3 occupies minimal board space and is ideal for portable and space-constrained applications. Its low supply current of 20µA (typical) makes it suitable for battery-powered applications, where power efficiency is crucial.

This supervisory circuit from Maxim Integrated is a reliable solution for system management in microcontrollers, computers, controllers, and intelligent instruments. Its robust design and ease of integration make it an excellent choice for safeguarding system integrity in a variety of industrial, consumer, and telecommunications applications.

With the MAX6336US20D3, designers can ensure their systems maintain proper functionality and recover gracefully from power disturbances, enhancing overall system reliability and performance.
