Frequently Asked Questions
What charge measurement accuracy does the LTC2941CMS8E#TRPBF achieve, and over what supply voltage range?
The LTC2941CMS8E#TRPBF achieves ±1% charge measurement accuracy using its internal coulomb counter, operating across a supply voltage range of 2.7V to 5.5V. This precision allows battery management systems to reliably estimate remaining capacity in single-cell Li-ion or Li-polymer packs.
How does the LTC2941CMS8E#TRPBF communicate with a host processor, and what alert features does it provide?
The LTC2941CMS8E#TRPBF uses a 2-wire I2C interface running at up to 400kHz to communicate charge accumulation and voltage data to a host MCU. It also provides adjustable threshold alerts for both accumulated charge and supply voltage, enabling the system to generate interrupts when the battery drops below a programmed level.
What is the quiescent current of the LTC2941CMS8E#TRPBF and why does it matter for battery runtime?
The LTC2941CMS8E#TRPBF draws only 105µA of quiescent current during active operation. In a 1000mAh battery, this parasitic current extends the self-discharge effect by only about 0.01% per hour, making the device suitable for always-on monitoring in portable and IoT applications where maximizing battery runtime is critical.
In which package does the LTC2941CMS8E#TRPBF ship, and what is the pin count?
The LTC2941CMS8E#TRPBF is housed in an 8-pin MSOP package (Mini Small Outline Package) with a body size of approximately 3mm x 5mm, making it compact enough for space-constrained portable device PCBs while still offering standard through-reflow SMT assembly compatibility.
