MAX6356TZUT+

Overview

The MAX6356TZUT+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 and VCC2. It includes a debounced manual reset input and operates from -40°C to +85°C. Supply current is 20µA, with a minimum power-on reset pulse width of 100ms.

Feature Summary

• Monitors multiple voltage rails simultaneously to ensure system reliability
• Provides active-low push-pull reset outputs for direct interface compatibility
• Includes a debounced manual reset input for user-initiated control

Applications

• Multi-rail embedded systems requiring simultaneous voltage supervision
• Portable devices needing low standby current consumption
• Industrial equipment operating in extended temperature environments

Procurement Notes

Verify the complete part number including suffixes such as T or TR, as these indicate specific packaging configurations like tape and reel. Confirm that the threshold voltages match the design requirements, particularly the adjustable channel. Ensure the manufacturer is identified correctly as Analog Devices Inc. or Maxim Integrated to avoid counterfeit components.

Selection Notes

Select this component when three distinct voltage levels require monitoring within a compact footprint. The adjustable threshold offers flexibility for non-standard rail voltages. Compare against the MAX6355 and MAX6357 if different output types or fixed thresholds are preferred. Verify that the push-pull output capability meets the drive requirements of the downstream logic.

Part Context

This part belongs to the MAX635x series of dual and triple-voltage supervisors designed for microprocessor applications. The series improves system accuracy compared to discrete solutions. Other members include the MAX6351 through MAX6360, offering various combinations of monitored inputs, reset outputs, and watchdog timers in SOT-23 packages.

FAQ

What is the function of the third input on the MAX6356?

The third input serves as an additional voltage monitor channel, allowing supervision of a third supply rail alongside two fixed-threshold inputs.

How does the manual reset input behave?

The manual reset input is debounced and TTL/CMOS compatible, allowing users to assert the reset outputs actively regardless of supply voltage conditions.
