bq75614-Q1 Automotive Precision Battery Monitor Texas Instruments bq75614-Q1 Automotive Precision Battery Monitor integrates shunt-resistor current sense measurement with highly accurate cell voltage measurements within 128µs for all cell channels. The system utilizes integrated front-end filters to implement simple, low voltage rated, differential RC filters on the cell input channels. The integrated, post-ADC, low-pass filters allow filtered DC-like voltage measurements.
