LTC2946CDE-1#PBF

Overview

The LTC2946CDE-1#PBF is a rail-to-rail system monitor manufactured by Analog Devices Inc., designed for measuring current, voltage, power, charge, and energy. It operates within a supply voltage range of 2.7V to 100V and includes a shunt regulator for supplies exceeding 100V. The device utilizes a 1.5kHz I2C interface for communication. It is housed in a 16-pin DFN EP package with an exposed pad, suitable for automotive applications.

Feature Summary

Rail-to-rail system monitoring capability for comprehensive electrical parameter measurement
Integrated shunt regulator supporting supply voltages above 100V
Low-speed 1.5kHz I2C interface for data communication

Applications

-48V system power monitoring using low-side sensing
Automotive power supply controllers and monitors
Charge and energy monitoring in negative power systems

Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the 16-pin DFN EP package type matches the target PCB footprint. Ensure the 1.5kHz I2C speed requirement aligns with the system controller capabilities. Check for automotive qualification status if required for the application environment.

Selection Notes

Select this component when low-speed I2C communication is sufficient for the monitoring requirements. The 1.5kHz interface limits data throughput compared to higher-speed variants. Consider the DFN EP package for thermal performance and space constraints. Verify that the 2.7V to 100V operating range covers the system's supply voltage variations.

Part Context

This part belongs to the LTC2946 family of single-phase energy meters. It shares core functionality with other variants like the LTC2946IMS-1 but differs in package type and I2C interface speed. The CDE-1 designation specifically denotes the DFN EP package and 1.5kHz I2C speed, distinguishing it from MSOP or high-speed I2C versions.
