LTC2936CGN

Supervisors Overview

The LTC2936CGN is a programmable hex voltage supervisor manufactured by Analog Devices Inc. It monitors up to six independent power supply inputs simultaneously. The device features I2C-programmable overvoltage and undervoltage thresholds with selectable ranges and increments for each channel. An integrated EEPROM stores configuration data, ensuring settings persist across power cycles. Each monitor includes a dedicated comparator output. The component operates within a temperature range of 0°C to +70°C and is housed in an SSOP-24 package.

Supervisors Feature Summary

• Simultaneous monitoring of up to six independent voltage rails
• I2C interface for programmable threshold configuration
• Non-volatile EEPROM storage for persistent settings
• Dedicated comparator outputs for each monitored channel

Supervisors Applications

• Multi-rail server power supply supervision
• Industrial control system voltage monitoring
• Telecommunications equipment power management
• Embedded systems requiring configurable reset logic

Supervisors Procurement Notes

Verify the specific suffix (e.g., #TRPBF vs #PBF) against the required packaging format, as these denote tape-and-reel versus tube quantities. Confirm the operating temperature grade matches the application environment. Ensure the I2C address configuration aligns with the system bus topology. Cross-reference the latest datasheet revision for any pinout or electrical characteristic updates before finalizing procurement orders.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltages is required without using discrete comparators. The I2C configurability allows for flexible threshold adjustments during production or field deployment. Consider the SSOP-24 package size constraints relative to the PCB layout. Verify that the open-drain outputs are compatible with the downstream logic levels and pull-up requirements of the host microcontroller or FPGA.

Supervisors Part Context

The LTC2936 belongs to Analog Devices' family of multi-supervisor ICs designed for complex power architectures. Unlike single-channel supervisors, it consolidates multiple monitoring functions into one package, reducing board space and component count. The integration of EEPROM distinguishes it from volatile-configurable counterparts, offering robustness against power loss. This series supports applications demanding precise and adaptable voltage supervision across diverse industrial and commercial environments.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users must consult official Analog Devices resources or authorized distributors for qualified alternatives. Direct replacements may require verification of pin compatibility, threshold accuracy, and communication protocol support.
