MAX6357TZUT+T

Overview

The MAX6357TZUT+T is a triple voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5 V and consumes only 20 uA of quiescent current. The device monitors three input voltages with selectable thresholds including 1.8 V, 2.5 V, 3 V, 3.3 V, and 5 V. It features active low push-pull outputs and provides a manual reset function. The reset delay time is specified at 280 ms. Overvoltage thresholds are available at 2.35 V and 3.14 V. The component is housed in an SOT-23-6 package and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Triple-channel voltage monitoring capability for multiple power rails
• Ultra-low power consumption suitable for battery-operated systems
• Manual reset input for system control flexibility
• Active low push-pull output configuration

Applications

• Portable electronic devices requiring multi-voltage supervision
• Battery-powered consumer electronics
• Industrial control systems with multiple power domains
• Embedded microprocessor reset circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeits. Confirm RoHS compliance status via official documentation before integration. Check current availability as the product lifecycle status may indicate limited supply or end-of-life conditions. Ensure packaging specifications match design requirements for surface mount assembly processes.

Selection Notes

Select this component when triple voltage supervision is required with low standby current constraints. Compare threshold options against specific rail voltages to ensure accurate detection. Consider the SOT-23-6 package size for space-constrained layouts. Evaluate the 280 ms reset delay against system startup timing requirements. Verify compatibility with manual reset logic if external control is needed.

Part Context

This part belongs to the MAX6357T series of triple voltage supervisors from Maxim Integrated. It is designed for applications needing simultaneous monitoring of three distinct power supplies. The series offers various threshold combinations to accommodate different voltage levels. It serves as a critical component for ensuring system stability by detecting under-voltage and over-voltage conditions across multiple rails.
