MAX6353MTUK+T

Overview

The MAX6353MTUK+T is a dual-channel voltage supervisor IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors two independent supply voltages and asserts an active-low, push-pull reset signal when thresholds are exceeded. The device features a manual reset input for system control and offers a fixed reset delay time of 180 ms. Key electrical parameters include threshold voltages of 2.32 V and 2.93 V, with a maximum operating supply voltage of 5.5 V. Accuracy is specified at 1.5%, and quiescent current is typically 20 uA. It operates within a temperature range of -40°C to +85°C and is housed in a compact SOT-23-5 surface-mount package.

Feature Summary

• Dual-channel voltage supervision with independent threshold monitoring
• Active-low push-pull reset output for robust logic interfacing
• Manual reset input capability for external system control
• Compact SOT-23-5 surface-mount packaging

Applications

• Portable electronic devices requiring multi-voltage monitoring
• Embedded systems with microcontroller power supervision
• Battery-operated equipment needing low-power oversight
• Industrial control units requiring reliable reset generation

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm exact threshold voltage variants match design requirements, as multiple versions exist within the series. Check RoHS compliance documentation for environmental standards. Ensure storage conditions adhere to moisture sensitivity levels for leaded packages. Validate pinout compatibility with existing PCB layouts before integration.

Selection Notes

Select this component when dual-supervision functionality is required in space-constrained designs. Consider the specific threshold voltages (2.32 V and 2.93 V) against target rail levels. Evaluate the 180 ms reset delay against system startup timing requirements. Assess the 20 uA quiescent current impact on overall battery life. Compare against single-channel alternatives if only one rail requires monitoring.

Part Context

This part belongs to the MAX6353L series of dual/triple-voltage supervisors from Maxim Integrated. It complements other variants like the MAX6353SZUK+T and MAX6354LTUK+T, which offer different threshold configurations. The series provides flexible power management solutions for applications requiring precise voltage oversight without complex programming interfaces.

Replacement Considerations

Direct substitutes include MAX6353SZUK+T and MAX6354LTUK+T, provided threshold voltages align with circuit requirements. Verify pinout compatibility across SOT-23-5 packages. Ensure functional equivalence regarding reset polarity and delay times. Cross-reference datasheets for any differences in accuracy specifications or operating temperature ranges.
