MAX6359LTUT+T

Overview

The MAX6359LTUT+T is a dual-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors two input voltages with thresholds of 3.08 V and 4.63 V, providing an active low, open-drain reset output. The device features a manual reset input, a watchdog timer, and a reset delay time of 180 ms. It operates within a supply voltage range up to 5.5 V, with a typical operating current of 20 uA. Accuracy is specified at 1.5%, and it supports overvoltage thresholds of 3.14 V and 4.72 V. The component is housed in a SOT-23-6 package and functions across a temperature range from -40 C to +85 C.

Feature Summary

• Dual-channel voltage supervision with factory-set threshold levels for precise monitoring
• Integrated watchdog timer functionality for system reliability
• Debounced manual reset input compatible with TTL/CMOS logic

Applications

• Microprocessor power supply monitoring
• Embedded system voltage supervision
• Portable electronic device power management

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices, as lifecycle status may indicate end-of-life conditions. Ensure packaging specifications match project requirements for surface mount installation.

Selection Notes

Select this component when dual independent voltage rails require simultaneous supervision with open-drain output compatibility. Consider the specific threshold values of 3.08 V and 4.63 V against target rail voltages. Evaluate the need for watchdog integration versus external solutions based on system complexity and pin count constraints.

Part Context

This part belongs to the MAX635xL series of microprocessor supervisory circuits designed for low-power applications. It shares functional similarities with other members like the MAX6358 and MAX6360 but differs in output type and channel configuration. The series emphasizes high accuracy and low quiescent current for battery-operated systems.
