LTC29491 Rev AFor more information FeedbackTYPICAL APPLICATION FEATURESDESCRIPTIONC urrent, Voltage, and Charge Monitor for high Voltage Battery PacksThe LT C 2949 is a high precision current, voltage, tem-perature, charge and energy meter for electrical and hybrid vehicles and other isolated current sense applications. It infers charge and energy flowing in and out of the battery pack by monitoring simultaneously the voltage drop over up to two sense resistors and the battery pack offset ADCs ensure accurate measurement of voltage and current with insignificant power loss. Con-tinuous integration of current and power ensures lossless tracking of charge and energy delivered or received by the battery built-in serial interface can be configured to support isolated isoSPI communication to the host or as SPI LTC2949 features 12 internally buffered high imped-ance inputs (V1 to V12) for measuring voltages from external sensors or resistor dividers allowing to measure temperatures, HV-Link voltages, chassis isolation and supervise contactor states.
