LTC2946CDE

Overview

The LTC2946CDE is a rail-to-rail system monitor designed to measure current, voltage, power, charge, and energy. It operates within a supply voltage range of 2.7V to 100V and includes an integrated shunt regulator for applications involving supplies exceeding 100V. The device utilizes a 1.5kHz I2C interface for communication. It is packaged in a 16-pin DFN EP format.

Feature Summary

Measures current, voltage, power, charge, and energy
Rail-to-rail system monitoring capability
Integrated shunt regulator for high-voltage supplies

Applications

-48V systems using low side sensing
Power monitoring
Charge monitoring
Energy monitoring

Procurement Notes

Verify the specific suffix (e.g., #PBF) against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure the 1.5kHz I2C interface requirement aligns with system design constraints. Confirm automotive qualification status if applicable to the target application environment.

Selection Notes

Select this component when rail-to-rail monitoring of multiple electrical parameters is required in systems operating between 2.7V and 100V. The integrated shunt regulator supports higher voltage inputs. Consider the 16-pin DFN EP package for space-constrained designs requiring thermal performance.

Part Context

The LTC2946CDE belongs to the LTC2946 family of power, charge, and energy monitors from Analog Devices. This family provides comprehensive system monitoring solutions with varying package options and interface speeds to suit different industrial and automotive applications.

Replacement Considerations

Check for other members of the LTC2946 family with compatible interfaces or packages. Verify functional equivalence regarding voltage ranges and measurement capabilities before substitution.
