LTC2946IMS-1#TRPBF

Overview

The LTC2946IMS-1#TRPBF is a wide-range power, charge, and energy monitor featuring an on-board ADC and I2C interface. It measures current, voltage, power, charge, and energy in rail-to-rail system applications. The device operates within a supply voltage range of 2.7V to 100V and includes a shunt regulator for handling supplies above 100V. This specific variant is packaged in a 16-pin MSOP tape and reel format.

Feature Summary

Measures current, voltage, power, charge, and energy with rail-to-rail input capability
Integrates an on-board ADC and supports I2C communication interfaces
Includes a built-in shunt regulator designed for high-voltage supply environments exceeding 100V

Applications

Wide range negative power monitoring from -4V to -500V
Bidirectional power monitoring with energy and charge tracking in forward paths
-48V harsh environment systems utilizing INTVCC shunt regulators for transient tolerance

Procurement Notes

Verify the suffix TRPBF confirms the tape and reel packaging configuration distinct from tube variants. Confirm the IMS-1 designation aligns with required automotive or industrial temperature specifications. Ensure the I2C address and register map match the target system design constraints before finalizing procurement orders.

Selection Notes

Select this component for applications requiring comprehensive energy and charge measurement alongside standard power monitoring. The integrated shunt regulator makes it suitable for high-voltage inputs without external level shifting. Consider the 16-pin MSOP package dimensions for PCB layout compatibility and thermal management requirements in dense designs.

Part Context

This part belongs to the LTC2946 family of single-channel energy monitors manufactured by Analog Devices Inc. It shares core functionality with other variants like the LTC2946IMS-1#PBF but differs in packaging format. The family provides rail-to-rail monitoring capabilities for various industrial and automotive power systems.
