Maxim Integrated MAX6336US16D3-T Microprocessor Supervisory Circuit

The MAX6336US16D3-T is a precision microprocessor (μP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with 3.3V-powered circuits. This supervisory circuit is particularly suitable for use in portable equipment, computers, controllers, and intelligent instruments, where maintaining the integrity of the operating voltage is crucial.

Key Features:

• Voltage Monitoring: The device keeps a close watch on the system voltage, ensuring that the microprocessor has a stable voltage supply. It asserts a reset signal whenever the VCC supply voltage falls below the factory-set reset threshold, 1.6V in this case.
• Reset Output: The reset output is available in active-low push-pull configuration, which provides a direct interface with a microprocessor's reset pin without needing external components.
• Reset Timeout: After the supply voltage rises above the reset threshold, the MAX6336US16D3-T maintains the reset output in the active state for a minimum timeout period to ensure the system microprocessor starts up with a clean reset.
• Low Power Consumption: Designed for energy-sensitive applications, this device consumes minimal power, which extends battery life in portable applications.
• Temperature Range: The supervisory circuit operates over a wide temperature range, making it suitable for various environments and applications.
• Small Footprint: Available in a compact SOT-323 package, the MAX6336US16D3-T saves valuable board space, which is essential for space-constrained designs.

Applications:

The MAX6336US16D3-T can be implemented in a wide array of applications where system reliability is paramount. Its primary function is to safeguard μP systems against the consequences of power failures, ensuring that the software controlling the μP does not attempt to execute with insufficient operating voltage. This makes it an ideal choice for portable devices, data loggers, embedded systems, and other critical electronic devices that require consistent monitoring and reliable operation.

Overall, the Maxim Integrated MAX6336US16D3-T supervisory circuit is a robust solution for enhancing system reliability, providing designers with a straightforward and cost-effective way to protect their digital systems.
