MAX6357TWUT+T

Overview

The MAX6357TWUT+T is a triple voltage supervisor integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors three independent supply rails with threshold voltages of 1.67 V, 3.08 V, and an adjustable setting. The device features an active-low push-pull output and supports manual reset functionality. It operates within a supply voltage range up to 5.5 V and maintains a low quiescent current of 20 uA. The component provides a minimum reset delay time of 100 ms and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Triple-channel voltage monitoring capability for independent power rail supervision
• Active-low push-pull output configuration for direct logic interface compatibility
• Manual reset input support allowing external control over system initialization states

Applications

• Multi-rail embedded system power management
• Microprocessor unit (MPU) supervisory circuits
• Industrial control board voltage monitoring

Procurement Notes

Verify component authenticity through authorized distribution channels due to discontinuation status. Confirm package integrity and storage conditions prior to implementation. Cross-reference datasheet specifications against current design requirements to ensure compatibility with existing voltage thresholds and timing constraints.

Selection Notes

Evaluate the specific threshold requirements for each monitored rail to determine if the fixed 1.67 V and 3.08 V settings align with system needs. Consider the adjustable channel flexibility for custom voltage levels. Assess the push-pull output drive strength against downstream load requirements and verify thermal performance within the specified operating temperature range.
