LTC2946HDE-1#TRPBF

Overview

The LTC2946HDE-1#TRPBF is a rail-to-rail system monitor manufactured by Analog Devices Inc., designed for precise measurement of current, voltage, power, charge, and energy. It features an operating supply range of 2.7V to 100V and includes a shunt regulator for supplies exceeding 100V. The device supports I2C interfaces with selectable speeds of 1.5kHz or 10kHz. Packaged in a 16-pin DFN EP, it operates within a temperature range of -40°C to +125°C and consumes a typical supply current of 700µA.

Feature Summary

Measures current, voltage, power, charge, and energy with rail-to-rail capability
Includes integrated shunt regulator for high-voltage applications above 100V
Supports flexible I2C interface configurations at 1.5kHz or 10kHz

Applications

Power, charge, and energy monitoring in -48V systems using low-side sensing
Bidirectional power monitoring with energy and charge tracking in the forward path
Wide-range negative power, charge, and energy monitoring from -4V to -500V

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm the H-grade designation aligns with required automotive or extended temperature specifications. Ensure the I2C address configuration matches the target system design constraints before finalizing procurement orders.

Selection Notes

Select this component for applications requiring comprehensive electrical parameter monitoring across wide voltage ranges. Consider the 16-pin DFN EP package for space-constrained designs. Evaluate the need for bidirectional monitoring capabilities if reverse power flow detection is required in the circuit topology.

Part Context

This part belongs to the LTC2946 family of single-channel energy monitors. It shares core functionality with variants like the LTC2946HMS and LTC2946IDE but differs in package type and specific interface speed options. The HDE-1 variant specifically targets high-voltage and automotive environments.
