MAX6356SVUT

Overview

The MAX6356SVUT+T is a triple-voltage microprocessor supervisor in a SOT-23-6 package. It monitors three supply rails with thresholds of 2.93V, 4.63V, and an adjustable input. The device features active-low push-pull reset outputs referenced to VCC1. It includes a debounced manual reset input and ensures output validity as long as any input exceeds +1.0V. Operating from -40°C to +85°C, it draws 20µA and provides a minimum 100ms power-on reset pulse width.

Feature Summary

• Monitors multiple voltage rails including two fixed thresholds and one adjustable input
• Provides active-low push-pull reset outputs referenced to the primary supply rail
• Includes a debounced manual reset input for system control
• Maintains valid reset states as long as any monitored supply remains above +1.0V

Applications

• Multi-rail embedded systems requiring simultaneous voltage supervision
• Microprocessor power-up sequencing and monitoring
• Industrial control units operating in extended temperature environments

Procurement Notes

Verify the complete part number suffix against official Analog Devices documentation to confirm specific threshold configurations and package variants. Ensure compatibility with the target PCB footprint for the SOT-23-6 package. Confirm RoHS compliance status if required by project specifications. Cross-reference the manufacturer's latest datasheet revision to ensure all electrical characteristics match design requirements before finalizing procurement orders.

Selection Notes

Select this component when a system requires supervision of three distinct voltage levels within a compact surface-mount form factor. The adjustable monitor input allows flexibility for non-standard voltage rails. Verify that the push-pull output drive capability meets the load requirements of the connected microprocessor or logic circuitry. Consider the 20µA quiescent current for battery-sensitive applications.

Part Context

The MAX6356 belongs to the MAX6351–MAX6360 family of dual/triple-voltage supervisors designed to improve system reliability over discrete solutions. This series integrates precision factory-set thresholds and manual reset functionality into small packages. The MAX6356 specifically adds a third voltage monitor compared to dual-channel counterparts, offering comprehensive power management for complex digital systems.

FAQ

How does the MAX6356 handle reset conditions when only one supply is active?

The reset outputs remain valid as long as either input supply voltage stays greater than +1.0V, ensuring continuous supervision even during partial power loss.

What is the reference level for the reset output?

The MAX6356 provides an active-low, push-pull reset output that is referenced to VCC1.
