LTC2936IUFD#PBF

Supervisors Overview

The LTC2936IUFD#PBF is an EEPROM-configurable voltage supervisor from Analog Devices Inc. designed to monitor up to six independent power supply inputs simultaneously. It utilizes a 24-pin QFN (4x5) package for surface-mount installation. The device features open-drain or open-collector outputs and includes configurable thresholds, reset delays, and watchdog timer functions. It operates within a specified temperature range suitable for industrial applications.

Supervisors Feature Summary

• Simultaneous monitoring of up to six power supply voltages
• EEPROM-based configuration for customizable thresholds and timing parameters
• Configurable watchdog timer with timeout detection
• Open-drain or open-collector output options

Supervisors Applications

• Multi-rail server and storage systems
• Industrial control equipment requiring complex power sequencing
• Telecommunications infrastructure power management
• Test and measurement instruments with multiple voltage domains

Supervisors Procurement Notes

Verify current availability status as distribution channels may report limited stock or end-of-life conditions. Confirm the specific revision level matches design requirements. Ensure ESD handling protocols are followed during assembly. Validate that the QFN-24 footprint aligns with PCB layout specifications before finalizing procurement orders.

Supervisors Selection Notes

Select this component when simultaneous multi-voltage supervision is required without external logic. The EEPROM configuration allows field adjustments, reducing inventory complexity compared to fixed-threshold supervisors. Consider the QFN-28 package constraints for thermal dissipation in dense layouts. Verify input voltage ranges match all monitored rails to ensure accurate threshold detection across the entire operating spectrum.

Supervisors Part Context

This part belongs to the LTC2936 family of multi-channel supervisors. It differs from single-channel devices by integrating six independent monitoring circuits into one IC. The IUD suffix indicates the industrial temperature grade and QFN package type. The #PBF designation confirms lead-free and RoHS compliance per manufacturer standards.

Supervisors FAQ

Can the reset thresholds be changed after manufacturing?

Yes, the LTC2936 uses internal EEPROM to store configuration data, allowing thresholds and timing parameters to be programmed via the serial interface after production.

What is the maximum number of inputs this device can monitor?

The device supports simultaneous monitoring of up to six independent power supply voltage inputs.
