MAX6352TWUK-T

Overview

The MAX6352TWUK-T is a dual-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors two independent power-supply inputs, asserting reset outputs if either voltage drops below its associated preset threshold. The device features precision factory-set thresholds for +2.5V, +3.0V, +3.3V, and +5V supplies. It operates with a supply current of 20µA and includes a debounced manual-reset input. The component is housed in a small 5-pin SOT-23 package.

Feature Summary

• Monitors multiple power-supply voltages to assert system reset upon undervoltage conditions
• Includes a debounced TTL/CMOS-compatible manual-reset input for user control
• Features power-supply transient immunity to ignore short glitches on monitored lines
• Guarantees valid RESET output status down to VCC levels as low as 1V

Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Intelligent instruments requiring multi-voltage supervision
• Portable and battery-powered equipment prioritizing low power consumption
• Controllers in multivoltage embedded systems

Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm the exact reset threshold voltages and package variant. Ensure the ordering information matches the required voltage monitoring specifications for your design. Confirm RoHS compliance status and availability through authorized distributors, as lead times may vary based on production schedules.

Selection Notes

Select this component when simultaneous monitoring of two distinct power rails is required within a compact footprint. It is suitable for designs needing guaranteed operation down to 1V on monitored inputs. Consider the 20µA supply current for battery-sensitive applications. Verify that the factory-set threshold options align with the target supply voltages without requiring external resistors.

Part Context

This part belongs to the MAX6351–MAX6360 family of microprocessor supervisors designed to improve system reliability. These devices replace separate ICs or discrete components by integrating multiple reset functions into a single chip. The series is characterized by precision thresholds and minimal external component requirements, making it a standard solution for power management in complex digital systems.

Replacement Considerations

Check the MAX6351 and MAX6353 variants within the same family for single or triple voltage monitoring needs. Verify pin compatibility and threshold voltage matching before substituting with other dual-supervisor ICs from different manufacturers.
