MAX6352LSUK

Overview

The MAX6352LSUK+ is a dual-voltage microprocessor supervisory circuit manufactured by Analog Devices (Maxim Integrated). It provides precision monitoring for two independent power-supply rails, featuring factory-set reset thresholds. The device operates with a supply current of 20µA and ensures system reliability by asserting active-low open-drain reset outputs when input voltages drop below preset levels. It includes a debounced manual reset input and supports operation over an extended temperature range.

Feature Summary

• Dual voltage supervision with precision factory-set thresholds
• Low quiescent current consumption for battery applications
• Active-low open-drain reset outputs valid down to 1V
• Debounced manual reset input compatible with TTL/CMOS

Applications

• Multivoltage computer systems
• Intelligent instruments
• Portable and battery-powered equipment
• Controllers requiring multiple power rails

Procurement Notes

Verify the specific suffix 'L' against official datasheets to confirm threshold voltage selections, as variations exist within the MAX6352 family. Confirm RoHS compliance status and lead times through authorized distributors, noting that availability may be limited due to product lifecycle status. Ensure the SOT-23-5 package matches your PCB footprint requirements before ordering.

Selection Notes

Select this component when simultaneous monitoring of two distinct voltage rails is required without external resistors. It is suitable for designs prioritizing low power consumption and high accuracy. Consider the MAX6352 series if watchdog timer functionality is not needed, or choose variants with different threshold combinations based on specific supply rail requirements.

Part Context

The MAX6352 belongs to a family of microprocessor supervisors designed to replace discrete components. It integrates multiple reset functions into a small SOT-23 package, improving system reliability compared to separate ICs. The series offers various threshold options and package configurations to suit diverse embedded system architectures.

Replacement Considerations

Direct substitutes include other MAX6352 variants with matching voltage thresholds and package types. Verify pin compatibility and electrical specifications before replacing. Cross-reference with Maxim Integrated's obsolescence notices for potential end-of-life implications.
