MAX6719UTVHD3

Supervisors Overview

The MAX6719UTVHD3 is a triple-channel voltage supervisor from Analog Devices Inc./Maxim Integrated, housed in an SOT-23-6 package. It features three independent monitoring channels with user-adjustable thresholds, including one fixed at 1.313V and two adjustable options. The device supports a maximum supply voltage of 5.5V and operates within a temperature range of -40°C to +85°C. It provides an active-low, open-drain output and includes manual reset functionality without a watchdog timer or battery backup switch. The quiescent current is 15µA.

Supervisors Feature Summary

• Provides three independent voltage monitoring channels for comprehensive power system supervision
• Features user-adjustable threshold voltages allowing customization for specific circuit requirements
• Delivers an active-low, open-drain output signal for direct interface with digital logic
• Supports manual reset functionality to allow external control over the reset state

Supervisors Applications

• Battery-powered IoT sensors requiring low quiescent current
• Wearable electronics needing compact SOT-23-6 packaging
• Industrial systems operating in harsh environments across extended temperature ranges
• Commercial applications requiring reliable multi-voltage supervision

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and lead-free specifications before integration. Ensure the SOT-23-6 package matches your PCB footprint design. Check for any obsolescence notices or lifecycle changes that may affect long-term availability. Validate electrical parameters against your specific application requirements.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous monitoring within a small form factor. The adjustable thresholds offer flexibility for various supply levels. Consider the 15µA quiescent current for battery-sensitive designs. Verify that the open-drain output aligns with your microcontroller input requirements. Ensure the operating temperature range meets your environmental conditions.

Supervisors Part Context

Part of the MAX6719 series of ultra-low-voltage supervisors designed for portable and industrial applications. The series emphasizes minimal power consumption and compact packaging. This specific variant offers triple-channel capability with mixed fixed and adjustable thresholds, distinguishing it from single or dual-channel alternatives in the same family.

Supervisors Replacement Considerations

Consult official documentation for verified substitute part numbers. Cross-reference pinouts and electrical characteristics carefully. Ensure compatibility with existing PCB layouts and firmware logic when considering alternative components.
