Frequently Asked Questions
What parameters does the LTC2943CDD#PBF measure and how does this simplify battery management design?
The LTC2943CDD#PBF simultaneously measures battery voltage, current via a sense resistor, and temperature in a single IC. By integrating 3 measurement functions with adjustable thresholds into one 8-pin DFN package, it replaces separate ADC, current sense amplifier, and temperature sensor ICs, reducing BOM count and PCB area in battery management systems.
Which battery chemistries and cell configurations are compatible with the LTC2943CDD#PBF?
The LTC2943CDD#PBF is designed for multicell battery stacks and is compatible with Li-Ion, Li-Polymer, NiMH, and other rechargeable chemistries. It supports battery voltages from 3.6 V to 18 V, covering 1S to 4S Li-Ion configurations, making it suitable for tablets, power tools, and medical device battery packs.
How do the adjustable thresholds of the LTC2943CDD#PBF protect the battery system during abnormal conditions?
The LTC2943CDD#PBF allows firmware-programmable thresholds for over-voltage, under-voltage, over-temperature, and over-current conditions. When any threshold is exceeded, the IC asserts an alert pin, allowing the host microcontroller to cut power or trigger a protection FET within microseconds, preventing cell damage and extending battery cycle life in portable and stationary energy storage applications.
