MAX6363PUT23+

Overview

The MAX6363PUT23+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices / Maxim Integrated. It operates within a supply voltage range of up to 5.5 V and features a threshold voltage of 2.5 V, with alternative options available at 3 V, 3.3 V, and 5 V. The device provides an active-low, open-drain output and includes a fixed reset delay time of 280 ms. It supports battery backup switching and monitors a single input without manual reset or watchdog timer functionality. Operating currents are specified at 15 uA, with power dissipation rated at 696 mW. The component functions reliably across a temperature range from -40 C to +85 C and is housed in an SOT-23-6 surface-mount package.

Feature Summary

• Provides reliable system reset supervision for microprocessors with low quiescent current consumption
• Includes dedicated battery backup switch capability to manage power source transitions
• Features active-low open-drain output compatible with standard digital logic interfaces

Applications

• Microprocessor system reset monitoring
• Battery-powered device power management
• Embedded controller supervision

Procurement Notes

Verify the exact suffix designation, as the provided model lacks the trailing 'T' often associated with tape-and-reel packaging in distributor listings. Confirm RoHS compliance status through official documentation. Check availability constraints, as some distributors indicate limited stock or discontinuation status for this specific part number variant.

Selection Notes

Select this component when a simple, low-power supervisor with battery backup support is required. Ensure the 2.5 V threshold aligns with the target system voltage. Verify that the open-drain output configuration suits the downstream logic requirements. Consider the SOT-23-6 package size for space-constrained designs.

Part Context

This part belongs to the MAX6363P series of low-power MPU supervisors. It is designed for applications requiring minimal standby current and basic reset functionality without complex timing or watchdog features. The series emphasizes reliability in portable and battery-operated electronics where power efficiency is critical.

Replacement Considerations

Check for MAX6363LUT23+T if push-pull output is preferred over open-drain. Verify pinout compatibility before substituting with other MAX6363 variants. Consult official cross-reference guides for equivalent parts with similar threshold voltages.
