Overview
The LTC2946IDE#TRPBF 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 2.7 V to 100 V and features an I2C interface with a speed of 10 kHz. The device is housed in a 16-pin DFN EP package and supports surface mount installation. It functions as a wide-range negative power, charge, and energy monitor, suitable for automotive applications.
Feature Summary
- Rail-to-rail system monitoring capability for comprehensive electrical parameter measurement
- Integrated I2C interface for digital communication and data retrieval
- Wide operating voltage range supporting high-side and low-side sensing configurations
Applications
- Automotive power supply monitoring systems
- Negative power, charge, and energy monitoring in industrial equipment
- Bidirectional power flow analysis in battery management contexts
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the IDE designation aligns with required temperature and performance grades. Ensure compatibility with existing I2C bus architectures before integration. Check for any recent product change notifications regarding package or material updates.
Selection Notes
Select this component for applications requiring precise measurement of multiple electrical parameters including charge and energy. The wide voltage range accommodates various supply rails without external level shifting. Consider the 16-pin DFN EP package for space-constrained designs requiring thermal dissipation capabilities.
Part Context
This part belongs to the LTC2946 series of system monitors from Analog Devices. It shares core functionality with other variants like the LTC2946HDE and LTC2946CMS-1 but differs in package type and specific operational characteristics. The series is designed for high-accuracy monitoring in demanding environments.
Replacement Considerations
Direct substitutes include other LTC2946 variants such as LTC2946IDE#PBF (tube packaging) or LTC2946HDE#TRPBF. Verify pinout and register compatibility before substitution. Package differences may require PCB layout adjustments.
