MAX6355RVUT

Overview

The MAX6355RVUT+T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2V to 5.5V and draws a typical quiescent current of 20µA. The device features two monitored inputs with threshold voltages of 2.63V and 4.38V, and overvoltage thresholds of 2.68V and 4.46V. It provides an active-low, open-drain reset output with a fixed 180ms reset delay time. Accuracy is specified at 1.5%. The component supports manual reset functionality and is housed in a compact SOT-23-6 package, suitable for surface-mount applications across an industrial temperature range of -40°C to +85°C.

Procurement Notes

Verify the complete part number including suffixes such as '+T' or '+TR' for tape-and-reel configuration. Confirm RoHS compliance status through official documentation. Check current lifecycle status as distribution availability may vary. Ensure the specific threshold voltage variants match design requirements before procurement.

Selection Notes

Select this component when multiple voltage rails require monitoring within a limited board space. The fixed threshold options simplify design compared to adjustable supervisors. Verify that the 180ms reset delay aligns with system startup timing requirements. Consider the open-drain output compatibility with downstream logic levels.

Part Context

This part belongs to the MAX6355 series of microprocessor supervisory circuits from Maxim Integrated. The series offers various threshold combinations and package options. The RVUT variant specifically denotes the SOT-23-6 package with particular threshold settings. This family is designed for reliable power management in embedded systems requiring precise voltage monitoring.

Replacement Considerations

Check for MAX6355 variants with different threshold voltages if exact specifications do not match. Verify pin-to-pin compatibility with alternative suppliers' offerings. Confirm functional equivalence regarding reset delay and output type before substitution.
