What are the key features of LTC6103IMS8#TRPBF?
- Dual current sense channels in a single 8-pin MSOP package, reducing BOM count and PCB area for 2-rail monitoring
- 60V common-mode input voltage range supports direct high-side sensing on 12V, 24V, and 48V automotive power rails
- 600µV maximum input offset voltage enables accurate shunt measurement with low-value resistors from 1 mΩ to 100 mΩ
- 0.17µA maximum bias current at 25°C minimizes error contribution on high-impedance shunt sense networks
What is LTC6103IMS8#TRPBF used for?
The LTC6103IMS8#TRPBF is suited for dual-rail current monitoring in automotive battery management systems, motor drive power stages, and 48V mild-hybrid power distribution units where high-side sensing up to 60V is required. Its dual-channel architecture enables simultaneous monitoring of charge and discharge current paths in lithium battery packs or independent monitoring of two motor phase currents in an 8-pin MSOP footprint. The 600µV input offset ensures milliamp-level current resolution even with shunt resistors as low as 10 mΩ in high-current industrial applications.

Frequently Asked Questions
What is the maximum common-mode voltage of LTC6103IMS8#TRPBF and which automotive bus voltages does it directly support?
The LTC6103IMS8#TRPBF supports a maximum common-mode input voltage of 60V, enabling direct high-side current sensing on 12V automotive starter batteries, 24V commercial vehicle buses, and 48V mild-hybrid power rails without requiring voltage-level shifting circuits. This 60V rating also provides headroom for load dump transients on 12V automotive networks that can momentarily spike to 40V or higher.
How does the 600µV input offset voltage of LTC6103IMS8#TRPBF affect shunt resistor selection in a 10A current sensor design?
With a 600µV maximum input offset, the LTC6103IMS8#TRPBF introduces a current measurement error equivalent to 600µV divided by the shunt resistance. For a 10 mΩ shunt sensing 10A (100 mV full-scale), the 600µV offset represents a 6% error, requiring either a larger shunt (e.g., 50 mΩ for 1.2% error) or system-level calibration to achieve sub-1% accuracy in automotive battery current measurement.
What efficiency advantage does integrating two current sense channels in LTC6103IMS8#TRPBF provide for a dual-motor drive design?
By integrating 2 independent current sense amplifiers in a single 8-pin MSOP package, LTC6103IMS8#TRPBF reduces the component count from 2 discrete single-channel ICs to 1 device, saving approximately 50% of PCB area allocated to current sensing in a dual-motor drive. This integration also eliminates the need for 2 separate bypass capacitor networks and reduces assembly cost per current sense channel in high-volume automotive production.
For a 48V e-bike or light EV application, when should a designer select LTC6103IMS8#TRPBF over a lower common-mode-rated current sense IC?
In a 48V e-bike or light EV battery pack, the bus voltage can reach 54V to 58V at full charge, exceeding the 45V or 50V common-mode ratings of lower-cost current sense amplifiers. LTC6103IMS8#TRPBF's 60V common-mode rating provides the necessary 2V to 6V margin above worst-case fully-charged bus voltage, preventing amplifier saturation or latch-up that would occur with parts rated below 60V in the same 48V nominal system.
