Overview
The LTC2946MPMS-1#TRPBF is a single-channel, rail-to-rail system monitor manufactured by Analog Devices Inc. in a 16-pin MSOP tape and reel package. It measures current, voltage, power, charge, and energy via an I2C interface. The device operates with supply voltages from 2.7V to 100V and includes an integrated shunt regulator for handling supplies exceeding 100V.
Feature Summary
- Monitors current, voltage, power, charge, and energy simultaneously
- Includes integrated shunt regulator for high-voltage applications above 100V
- Supports bidirectional power monitoring capabilities
Applications
- Power, charge, and energy monitoring for main power supplies
- Power monitoring for secondary or auxiliary power supplies
- Bidirectional power monitoring systems
Procurement Notes
Verify the specific suffix #TRPBF confirms the tape and reel packaging format required for automated surface-mount assembly processes. Confirm that the MPMS-1 designation aligns with the intended main and auxiliary supply monitoring configuration rather than standard single-supply variants.
Selection Notes
Select this component when simultaneous measurement of electrical parameters including charge and energy is required alongside standard power monitoring. The integrated shunt regulator makes it suitable for environments where input voltages may exceed the standard 100V operating limit without external protection circuitry.
Part Context
This part belongs to the LTC2946 family of wide-range I2C power monitors. While the base LTC2946 provides general monitoring, the MPMS-1 variant is specifically characterized for dual-supply scenarios, enabling main supply energy tracking and auxiliary supply power monitoring within a single integrated circuit solution.

FAQ
How does the device handle input voltages above 100V?
The LTC2946MPMS-1 includes an integrated shunt regulator designed to tolerate and manage supply voltages exceeding 100V.
What is the primary function of the MPMS-1 variant compared to standard models?
It is configured to monitor both a main supply for energy/charge and a secondary supply for power using a single device.
