Maxim Integrated MAX6368BCPA Microprocessor Supervisory Circuit

The Maxim Integrated MAX6368BCPA 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 and battery control functions.

This supervisory circuit is particularly well-suited for use in portable equipment, computers, controllers, and intelligent instruments, where it ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6368BCPA operates over a wide voltage range and offers several features that make it a versatile component for any design that requires precise monitoring and reset capabilities.

Key Features:

• Voltage Monitoring: The device monitors the system voltage and maintains a reset output until the system voltage has stabilized above the reset threshold level for a preset timeout period.
• Programmable Watchdog Timer: A watchdog timer is included to ensure that the µP does not hang in an uncontrolled state. The timer can be programmed by the user to meet specific system requirements.
• Manual Reset Input: An additional feature is the manual reset input that allows for a reset to be triggered with an external pushbutton or logic signal.
• Low Power Consumption: Designed for power-sensitive applications, the MAX6368BCPA consumes minimal power, which is critical for extending battery life in portable devices.
• Immune to Short VCC Transients: The device is designed to ignore short transients on the VCC line, which helps prevent false triggering of the reset signal.

Package and Temperature:

The MAX6368BCPA comes in an 8-pin DIP package, making it easy to integrate into a variety of circuit board layouts. It is designed to operate over the extended industrial temperature range, ensuring reliable performance in challenging environmental conditions.

With its combination of features, the MAX6368BCPA from Maxim Integrated is an excellent choice for designers looking to improve the reliability and performance of their systems with a robust supervisory circuit.
