LTC2966HSW#PBF

Supervisors Overview

The LTC2966HSW#PBF is a low current, high voltage dual channel voltage monitor manufactured by Analog Devices Inc. It features internal high-value resistors to sense input monitor pins, enabling compact design. The device operates with supply voltages up to 100V and monitors two independent channels. It utilizes factory-set reset thresholds to supervise voltages ranging from 1.1V to 5V. The component is housed in a 20-SOIC package and supports surface mount installation. It functions within an operating temperature range of -40°C to 125°C (TA).

Supervisors Feature Summary

• Dual channel voltage monitoring capability for supervising multiple power rails simultaneously.
• High voltage operation supporting input monitor pins up to 100V with integrated sensing resistors.
• Factory-set reset thresholds eliminate the need for external precision components for voltage supervision.
• Low current consumption design suitable for energy-efficient and safety-critical applications.

Supervisors Applications

• Robust power-system supervision in safety-critical automotive applications.
• Monitoring voltages from 1.1V to 5V in industrial control systems.
• Supervisory circuits for multi-rail power distribution units.

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the selected variant matches the required package type and temperature rating for the target environment. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity. Check for any recent product change notices that may affect compatibility or performance specifications.

Supervisors Selection Notes

Select this component when dual-channel supervision of high-voltage inputs is required without external resistor networks. Consider the 100V input tolerance and factory-set thresholds for simplified design. Evaluate the 20-SOIC package constraints against board space requirements. Confirm that the operating temperature range meets the environmental conditions of the final application.
