LTC2946IMS-1#PBF

Overview

The LTC2946IMS-1#PBF is a single-channel, rail-to-rail system monitor manufactured by Analog Devices Inc. It measures current, voltage, power, charge, and energy via an I2C interface. The device operates within a supply voltage range of 2.7V to 100V and includes an integrated shunt regulator for handling supplies above 100V. It is housed in a 16-pin MSOP package.

Feature Summary

Rail-to-rail system monitoring capability for comprehensive electrical parameter measurement
Integrated on-board ADC with I2C digital interface for data communication
Built-in shunt regulator designed to tolerate high-voltage transients exceeding 100V

Applications

Monitoring wide-range negative power supplies such as -48V telecom systems
Bidirectional power monitoring with energy and charge tracking in forward paths
Harsh environment applications requiring tolerance for high-voltage transients up to 200V

Procurement Notes

Verify the specific suffix '-1' indicates the required shunt regulator configuration for high-voltage transient tolerance. Confirm the 'MSOP' package type matches the PCB footprint requirements. Ensure the '#PBF' designation aligns with lead-free manufacturing standards if applicable to the assembly process.

Selection Notes

Select this component when precise measurement of power, charge, and energy is required alongside standard voltage and current monitoring. The integrated shunt regulator makes it suitable for systems where the main supply may experience significant overvoltage events or exceeds the standard operating limit.

Part Context

This part belongs to the LTC2946 family of power, charge, and energy monitors. The IMS-1 variant specifically denotes the MSOP package and the inclusion of the internal shunt regulator feature, distinguishing it from variants without this protection mechanism.

Replacement Considerations

LTC2946IMS#PBF serves as a direct substitute if the integrated shunt regulator for high-voltage transients is not required for the specific application design.
