The MAX6303CUA+ is a highly reliable and versatile microprocessor (µP) supervisory circuit designed and manufactured by Maxim Integrated. This compact device is engineered to monitor power supplies in µP and digital systems, providing excellent circuit reliability and low cost by eliminating the need for external components.

Key Features

• Reset Output: The device features an active-low reset output, which ensures that the µP starts in a known state. The reset signal remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level, providing ample time for the system to stabilize.
• Voltage Monitoring: This supervisory circuit can monitor a +3V, +3.3V, or +5V power supply without the need for external components. Its precision is remarkable, with a factory-set reset threshold voltage accuracy at ±1.5% over the entire temperature range.
• Low Power Consumption: With a quiescent current of only 20µA (typical), the MAX6303CUA+ is an energy-efficient solution for battery-operated applications.
• Compact Form Factor: The device comes in an 8-pin µMAX package, which is highly space-efficient, making it ideal for use in systems where board space is at a premium.
• Temperature Range: It operates over a wide temperature range of -40°C to +85°C, suitable for industrial applications.
• Manual Reset Input: An additional feature includes a debounced manual reset input that allows for a manual system reset.

Applications

The MAX6303CUA+ is suitable for a wide array of applications where reliable system operation is critical. It is commonly used in:

• Computers
• Controllers
• Intelligent Instruments
• Portable/Battery-Powered Equipment
