Frequently Asked Questions
How accurate is the LTC2941IMS8E#PBF coulomb counter for Li-Ion battery charge tracking?
The LTC2941IMS8E#PBF achieves ±2% charge measurement accuracy over the full operating voltage range of 2.7 V to 5.5 V. This precision is sufficient for consumer and automotive Li-Ion battery management systems requiring reliable state-of-charge estimation across the battery's full discharge cycle.
What communication interface does the LTC2941IMS8E#PBF use and what data does it provide?
The LTC2941IMS8E#PBF uses a 2-wire I2C interface to report accumulated charge in coulombs, battery voltage, and temperature to a host microcontroller. Adjustable charge threshold registers allow the host to set low and high charge alarm levels, triggering an alert pin when battery charge falls outside the programmed 8-bit window.
Is the LTC2941IMS8E#PBF suitable for automotive battery monitoring designs operating across wide temperature ranges?
Yes, the LTC2941IMS8E#PBF is rated for operation from -40°C to 125°C in an MSOP-8 package, meeting automotive temperature requirements. Its AEC-Q100 compatible design makes it suitable for battery monitoring in electric vehicles, start-stop systems, and infotainment power management where reliability over 125°C is mandatory.
