LTC2946MPMS-1#PBF

Overview

The LTC2946MPMS-1#PBF is a single-phase energy monitor IC manufactured by Analog Devices Inc., housed in a 16-MSOP package. It measures current, voltage, power, charge, and energy with a measurement error of 0.5%. The device operates on a supply voltage range of 2.7 V to 100 V and draws a supply current of 900 µA. It supports an operating temperature range from -40°C to 125°C and features an I2C interface for communication.

Feature Summary

Rail-to-rail system monitoring capability for comprehensive electrical parameter measurement
Integrated shunt regulator designed to handle supply voltages exceeding 100V
High accuracy measurement performance with specified low measurement error

Applications

Main supply power, charge, and energy monitoring
Secondary supply power monitoring using a single LTC2946 configuration
Bidirectional power monitoring with energy and charge tracking in the forward path

Procurement Notes

Verify the specific suffix MSMS against official Analog Devices documentation to confirm the exact variant specifications. Ensure compatibility with the required 16-MSOP package and industrial temperature range. Cross-reference the part number with the latest datasheet to validate any recent manufacturing changes or material declarations before finalizing procurement orders.

Selection Notes

Select this component when high-accuracy monitoring of main and auxiliary supplies is required within a single chip solution. The integrated shunt regulator allows operation in harsh environments with high transient voltages. Consider the 16-MSOP package constraints and the specific supply current requirements for low-power applications.

Part Context

This part belongs to the LTC2946 family of wide-range power, charge, and energy monitors. It shares core functionalities with variants like the LTC2946IMS-1 and LTC2946CMS-1 but is specifically designated for main and secondary supply monitoring configurations. The family utilizes an onboard ADC and I2C interface for data retrieval.
