MAX6719UTLTD1+

Supervisors Overview

The MAX6719UTLTD1+T is a triple ultra-low-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors three system power-supply voltages and asserts a reset if any supply falls below its threshold. The device features an active-low, open-drain output and supports manual reset input. It operates within a supply voltage range of 1.8V to 5V with thresholds adjustable from 900mV to 3.3V. Key electrical parameters include a maximum supply voltage of 5.5V, a quiescent current of 15µA, and a reset delay time of 2.2ms. The component is housed in a SOT-23-6 package and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Triple-channel voltage supervision for enhanced system reliability
• Adjustable reset thresholds covering low-voltage applications
• Ultra-low quiescent current for power efficiency
• Manual reset capability via dedicated input pin

Supervisors Applications

• Portable electronic devices requiring multi-rail power monitoring
• Battery-operated systems needing extended operational life
• Embedded controllers with strict size constraints
• Industrial equipment operating in variable thermal environments

Supervisors Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct threshold settings and package type. Confirm availability status as many variants are marked obsolete or have limited stock. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Check RoHS compliance documentation for regulatory adherence in target markets.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltage rails is required in a compact form factor. Consider the adjustable threshold feature if fixed internal references do not match system requirements. Evaluate the 15µA quiescent current against total system power budgets. Ensure the SOT-23-6 footprint aligns with existing PCB layout constraints.

Supervisors Part Context

This part belongs to the MAX6719 family of dual and triple supervisory circuits designed for ultra-low-voltage applications. It complements other Maxim Integrated PMIC solutions by providing reliable reset generation without complex external components. The series is known for integrating multiple supervisor functions into small packages, reducing board space compared to discrete implementations.
