LTC2936CGN#PBF

Supervisors Overview

The LTC2936CGN#PBF is an EEPROM-configurable hex voltage supervisor manufactured by Analog Devices. It simultaneously monitors up to six power supply inputs, providing I2C-programmable overvoltage and undervoltage thresholds with adjustable ranges and increments. The device features two general-purpose inputs (GPI) and three general-purpose input/output pins (GPIO). It includes internal EEPROM for autonomous configuration without software support. The component operates within a supply voltage range of 3.4V to 13.9V and is housed in a 16-pin SSOP package.

Supervisors Feature Summary

• Simultaneous monitoring of up to six independent power supply voltages
• I2C/SMBus interface for programmable threshold adjustments and configuration
• Internal EEPROM retains fault snapshots and settings for autonomous operation
• Configurable general-purpose inputs and outputs for system flexibility

Supervisors Applications

• High availability computer systems
• Network servers
• Telecom equipment
• Data storage systems

Supervisors Procurement Notes

Verify the specific suffix (#PBF indicates lead-free tape and tube packaging) against your Bill of Materials. Confirm that the 16-pin SSOP package matches your PCB footprint requirements. Ensure your design supports the I2C interface protocol required for programming the thresholds and accessing status registers via the onboard EEPROM.

Supervisors Selection Notes

Select this component when multi-rail supervision is required in a compact form factor. It is suitable for designs needing precise, software-adjustable trip points rather than fixed hardware thresholds. Consider the I2C bus speed and addressability if multiple supervisors are daisy-chained or used in parallel within the same system architecture.

Supervisors Part Context

This part belongs to the LTC2936 family of voltage supervisors from Analog Devices. These devices are designed for complex power management applications where monitoring multiple rails is critical. The CGN variant specifically denotes the commercial temperature range and SSOP package style, distinguishing it from other package options like DFN available in the broader product line.
