LTC2936IUFD#TRPBF

Supervisors Overview

The LTC2936IUFD#TRPBF is a supervisory circuit featuring an integrated EEPROM for programmable configuration. It monitors up to six independent power supply voltages simultaneously within a 1.0V to 5.5V range. The device provides open-drain or active-low reset outputs and includes a comparator output for custom threshold detection. Operating from a single supply, it functions reliably across the industrial temperature range of -40°C to +85°C in a compact 24-lead QFN package.

Supervisors Feature Summary

• Simultaneous monitoring of up to six distinct voltage rails
• EEPROM-based configuration for flexible threshold settings
• Configurable reset output polarity and comparator functionality

Supervisors Applications

• Multi-rail server and storage system power supervision
• Industrial control board voltage monitoring
• Telecommunications infrastructure power management

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the IUD variant designation corresponds to the industrial temperature grade (-40°C to +85°C). Ensure compatibility with the target PCB footprint for the 24-lead QFN package before finalizing procurement orders.

Supervisors Selection Notes

Select this component when designing systems requiring centralized monitoring of multiple voltage domains without external comparators. The EEPROM feature allows field-adjustable thresholds, reducing hardware revisions. Verify that the required number of monitored channels does not exceed six and that the supply voltage range aligns with the system's rail specifications.

Supervisors Part Context

This part belongs to Analog Devices' LTC2936 family of hex voltage supervisors. It serves as a comprehensive solution for complex power architectures where space and component count are critical constraints. The integration of configuration memory distinguishes it from fixed-threshold competitors.

Supervisors Replacement Considerations

Direct substitutes include other hex voltage supervisors from Analog Devices such as the LTC2937 series, which offers similar multi-channel monitoring capabilities. Cross-reference pinouts and EEPROM programming interfaces to ensure functional equivalence in existing designs.
