MAX6356TWUT

Overview

The MAX6356TWUT+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed to monitor multiple power-supply voltages for improved system reliability. It features three monitored voltage inputs with preset thresholds of 2.93V, 4.63V, and an adjustable threshold. The device provides active-low reset outputs in a push-pull configuration referenced to VCC1. It operates within a supply voltage range up to 5.5V and includes a debounced manual reset input. The component ensures valid outputs as long as any input remains above +1.0V and offers a minimum power-on reset pulse width of 100ms.

Feature Summary

• Monitors up to three distinct power-supply voltages simultaneously
• Provides active-low push-pull reset outputs referenced to VCC1
• Includes a debounced manual reset input compatible with TTL/CMOS logic
• Maintains valid output states when any monitored voltage exceeds +1.0V

Applications

• Monitoring dual or triple voltage rails in embedded systems
• Ensuring system stability in industrial control applications
• Providing reset signals for microprocessors in portable devices

Procurement Notes

Verify the specific suffix (e.g., +T) against the manufacturer's official part numbering guide to confirm package type and tape/reel specifications. Ensure the selected variant matches the required voltage thresholds and temperature range for your application design.

Selection Notes

Select this component when simultaneous monitoring of three voltage levels is required. Consider the fixed thresholds of 2.93V and 4.63V alongside the adjustable channel. Verify compatibility with the target system's logic levels and ensure the SOT-23-6 package fits the PCB layout constraints.

Part Context

The MAX6356 belongs to the MAX6351–MAX6360 series of microprocessor supervisors from Maxim Integrated. This family improves system accuracy compared to discrete components. The MAX6356 specifically distinguishes itself by offering an additional voltage monitor input compared to the dual-input variants like the MAX6351, making it suitable for more complex power architectures.
