MAX6353TWUK+T

Overview

The MAX6353TWUK+T is a dual-voltage microprocessor supervisory circuit in a SOT-23-5 package. It monitors two input supplies with factory-set thresholds of 1.67V and 3.08V. The device features an active-low, push-pull reset output referenced to VCC1 and a debounced manual reset input. It operates within a supply voltage range of 1.2V to 5.5V and includes a reset delay time of 180ms. The component functions over an extended temperature range from -40°C to +85°C.

Feature Summary

• Monitors multiple power-supply voltages with precision factory-set thresholds
• Provides active-low, push-pull reset outputs for system reliability
• Includes a debounced TTL/CMOS-compatible manual-reset input

Applications

• Embedded microprocessor systems requiring multi-rail supervision
• Edge computing hardware power management
• Industrial control units operating in extended temperature environments

Procurement Notes

Verify availability status as the component may be subject to limited supply or special order constraints. Confirm the specific suffix 'TWUK' matches the required threshold levels and package type. Check RoHS compliance documentation for current manufacturing standards. Ensure the datasheet revision aligns with the design requirements before finalizing procurement orders.

Selection Notes

Select this part when monitoring two distinct voltage rails with fixed thresholds of 1.67V and 3.08V is required. The SOT-23-5 package suits space-constrained designs. Consider the 180ms reset delay and active-low output polarity for compatibility with the target microprocessor reset logic. Verify that the 1.2V to 5.5V operating range covers all system supply variations.

Part Context

This component belongs to the MAX6351–MAX6360 series of dual/triple-voltage microprocessor supervisors. These devices improve system reliability by replacing discrete components with integrated monitoring solutions. The series offers various threshold combinations and package options, including 5-pin and 6-pin SOT-23 variants, designed for extended industrial temperature ranges.

Replacement Considerations

Cross-reference with other MAX635x series parts if different voltage thresholds are needed. Verify pinout compatibility between SOT-23-5 supervisor variants. Check for updated Analog Devices recommendations for legacy Maxim Integrated components.
