LTC2914IGN-1#PBF

Supervisors Overview

The LTC2914IGN-1#PBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring four independent voltage rails. It supports both undervoltage and overvoltage detection with separate positive and negative thresholds for each channel. The device operates within a supply voltage range of 2.7V to 5.5V and features a low quiescent current of 70µA. It utilizes an I2C-compatible serial interface for configuration and status reading, housed in a 16-lead SSOP package suitable for surface mount applications.

Supervisors Feature Summary

• Four-channel simultaneous voltage monitoring capability
• Independent programmable undervoltage and overvoltage thresholds
• Serial interface for register access and fault logging
• Low power consumption design for battery efficiency

Supervisors Applications

• Multi-rail power supply supervision in industrial systems
• Voltage monitoring for embedded processor boards
• Fault detection in telecommunications equipment
• Power management in portable electronic devices

Supervisors Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to ensure correct package type and temperature grade. Confirm that the IGN-1 designation matches the required SSOP-16 package and commercial temperature range specifications before procurement. Cross-reference with authorized distributors to validate authenticity and avoid counterfeit components.

Supervisors Selection Notes

Select this component when multi-channel voltage supervision is required with minimal board space. The integrated serial interface reduces pin count compared to parallel alternatives. Ensure the input voltage range aligns with the system rails. Consider the 70µA quiescent current impact on overall system power budget during active and standby modes.

Supervisors Part Context

This part belongs to the LTC2914 series of supervisory circuits. It shares functional similarities with other members like the LTC2912 but offers increased channel density. The series provides flexible threshold programming options. It complements Analog Devices' portfolio of power management ICs focused on system reliability and fault protection.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the same family such as the LTC2914CTS8-1#PBF if package size constraints differ. Verify compatibility of the serial interface protocol and threshold settings. No alternative part numbers are confirmed in the provided source data.
