Analog Devices LTC2949 | Demoboard DC2732A
Current, Voltage & Charge Monitor for High Voltage Battery Packs
Overview
| Topology | Other Topology |
Description
The LTC2949 is a high precision current, voltage, temperature, 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 voltage.Low offset ΔΣ ADCs ensure accurate measurement of voltage and current with insignificant power loss. Continuous integration of current and power ensures lossless tracking of charge and energy delivered or received by the battery pack.The built-in serial interface can be configured to support isolated isoSPI communication to the host or as SPI interface.The LTC2949 features 12 internally buffered high impedance 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. LTC2949 has up to five programmable digital outputs which can be set to ground, supply or toggling at 400kHz.
