MAX6356UVUT-T

Overview

The MAX6356UVUT-T is a microprocessor supervisor IC manufactured by Analog Devices Inc./Maxim Integrated. It features three monitored voltage inputs with thresholds of 2.93V, 4.63V, and an adjustable setting. The device provides active-low push-pull reset outputs referenced to VCC1. Key electrical parameters include a minimum power-on reset pulse width of 100ms and a supply current of 20µA. It operates within a temperature range of -40°C to +85°C and is housed in a surface-mount SOT-23-6 package.

Feature Summary

• Monitors multiple power-supply voltages including standard levels like +1.8V, +2.5V, +3.0V, +3.3V, and +5V.
• Includes a debounced manual-reset input compatible with TTL/CMOS logic levels.
• Maintains valid reset outputs as long as any input supply voltage remains above +1.0V.

Applications

• Monitoring dual or triple voltage rails in embedded systems
• Ensuring system reliability in portable electronic devices
• Providing power supervision for microprocessor-based circuits

Procurement Notes

Verify the specific suffix 'UVUT' against the manufacturer's official part numbering guide to confirm exact threshold configurations and packaging details. Confirm RoHS compliance status and ensure the component matches the required operating temperature range for your application environment before finalizing procurement.

Selection Notes

Select this component when precise monitoring of three distinct voltage rails is required. The adjustable threshold offers flexibility for non-standard voltage levels. Ensure the design accommodates the active-low push-pull output configuration and the 100ms minimum reset pulse width timing requirements.

Part Context

This component belongs to the MAX6351–MAX6360 series of microprocessor supervisors. These devices are designed to improve system reliability compared to discrete components. The series typically includes variants with watchdog timers or different output configurations, but the MAX6356 specifically focuses on triple voltage monitoring without an integrated watchdog timer.

FAQ

What is the reference voltage for the reset output?

The reset output is active-low and push-pull, referenced to VCC1.

Does the MAX6356 include a watchdog timer?

No, the MAX6356 does not offer a watchdog-timer input; this feature is available in other series members like the MAX6358.
