LTC2936IGN

Supervisors Overview

The LTC2936IGN is a six-channel voltage supervisor integrated circuit manufactured by Analog Devices Inc. It monitors up to six positive supply voltages simultaneously, comparing each input against an internal reference tied to ground. The device features adjustable or selectable voltage thresholds ranging from 200 mV to the supply voltage. It provides open-drain or open-collector outputs for fault indication. The component is housed in a 24-lead SSOP package and operates within standard industrial temperature ranges.

Supervisors Feature Summary

• Simultaneous monitoring of six independent positive voltage rails
• Adjustable threshold detection with selectable hysteresis options
• Open-drain output configuration for flexible logic interfacing
• Internal reference source eliminates need for external precision references

Supervisors Applications

• Multi-rail power supply supervision in industrial control systems
• Voltage monitoring in telecommunications equipment
• Fault detection in embedded computing platforms
• Power management in automotive electronic control units

Supervisors Procurement Notes

Verify the specific suffix (e.g., IGN vs. IGR) to confirm package type and temperature range. Confirm RoHS compliance status through official manufacturer documentation. Ensure the selected variant matches the required operating voltage range and output configuration for your design. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple positive voltages is required without external comparators. Consider the SSOP package size constraints and thermal performance. Verify that the adjustable threshold range covers all monitored rail voltages. Check if the open-drain output interface aligns with the downstream logic levels of the system microcontroller or FPGA.

Supervisors Part Context

This part belongs to the LTC2936 family of programmable hex voltage supervisors. It serves as a comprehensive solution for complex power architectures where multiple rails must be tracked for stability. The device integrates multiple supervisor functions into a single compact package, reducing board space compared to discrete solutions.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the Analog Devices portfolio such as the LTC2937 series for extended feature sets. Verify electrical parameter equivalence before substituting with components from other manufacturers. Ensure any replacement supports the same number of monitored channels and output drive capabilities.
