LTC2936CUFD#TRPBF

Supervisors Overview

The LTC2936CUFD#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple power rails in embedded systems. It features six independently programmable voltage monitor channels, allowing precise threshold detection for various supply lines. The device integrates an on-chip EEPROM to store configuration data, ensuring settings persist across power cycles. It operates within a temperature range of 0°C to +70°C and is housed in a compact 24-pin VQFN package with exposed pad (4x5 mm). Key electrical characteristics include support for input voltages up to 13.9V per channel and low quiescent current consumption, making it suitable for space-constrained applications requiring reliable multi-voltage supervision.

Supervisors Feature Summary

• Six independently programmable voltage monitor channels for comprehensive power rail supervision
• Integrated non-volatile EEPROM for persistent storage of user-defined threshold configurations
• Compact 24-pin VQFN package design optimized for high-density PCB layouts

Supervisors Applications

• Multi-rail power monitoring in industrial control systems
• Voltage supervision in telecommunications infrastructure equipment
• Power management in embedded computing platforms

Supervisors Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the CUFD designation corresponds to the commercial temperature grade and QFN package variant required for your design. Ensure compatibility with your board's thermal dissipation requirements given the exposed pad structure. Cross-reference the manufacturer's latest datasheet revision to confirm pinout and electrical specifications match your schematic before finalizing procurement orders.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous monitoring of up to six distinct voltage levels without external comparators. The integrated EEPROM simplifies production programming compared to devices requiring external memory or fixed thresholds. Consider the 0°C to +70°C operating range to ensure suitability for commercial environments. Evaluate the 24-pin footprint against available board space, noting the 4x5 mm dimensions. This part is appropriate where reducing component count and BOM complexity is prioritized over extreme temperature operation.

Supervisors Part Context

The LTC2936 belongs to Analog Devices' family of advanced supervisory circuits, specifically engineered for complex power architectures. Unlike single-channel monitors, this hex-channel device consolidates multiple functions into one IC. The CUFD#TRPBF variant represents the commercial grade version in a lead-free, halogen-free tape-and-reel format. It complements other PMIC offerings by providing granular voltage oversight essential for system stability and fault detection in modern electronic designs.

Supervisors Replacement Considerations

Direct substitutes may include other hex-channel supervisors from Analog Devices such as the LTC2936IGN#PBF, though package differences exist. Verify pin-to-pin compatibility if replacing with devices from other manufacturers. Ensure any alternative supports similar voltage ranges and EEPROM functionality to maintain design integrity without schematic modifications.
