MAX6353RVUK+T

Overview

The MAX6353RVUK+T is a dual-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors two input supply voltages and asserts active-low, push-pull reset outputs when any monitored voltage drops below its preset threshold. The device features a debounced manual reset input and operates with a reset delay time of 180 ms. It supports threshold voltages including 2.32 V and 2.93 V, ensuring system reliability by maintaining valid outputs as long as either input remains above +1.0 V.

Feature Summary

• Dual-input voltage monitoring with active-low push-pull reset outputs referenced to specific supply rails
• Debounced manual reset input compatible with TTL/CMOS logic levels
• Factory-set precision reset thresholds for multiple standard power-supply voltages
• Operates over the extended temperature range from -40°C to +85°C

Applications

• Microprocessor system power supervision
• Portable equipment voltage monitoring
• Battery-powered systems requiring reliable reset generation

Procurement Notes

Verify availability status carefully, as this component may be subject to limited supply or obsolescence. Confirm the exact suffix UK+T matches your design requirements. Check current distributor stock levels and lead times before finalizing procurement plans. Ensure RoHS compliance documentation is available if required for your manufacturing process.

Selection Notes

Select this part when dual-voltage supervision is required in a compact SOT-23-5 package. It is suitable for applications needing precise factory-set thresholds without external resistors. Consider the 180 ms reset delay and active-low output polarity during interface design. Verify that the monitored voltages fall within the specified operating range and threshold options.

Part Context

This component belongs to the MAX6351–MAX6360 series of dual/triple-voltage supervisory circuits. These devices improve system reliability compared to discrete solutions by integrating multiple reset functions into a single IC. The series offers various threshold combinations and package options to accommodate different multi-rail power architectures.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX635x family with matching threshold voltages. Verify that alternative parts offer identical reset delay times and output configurations. Ensure thermal and electrical specifications meet the original design constraints.
