Texas Instruments BQ756506-Q1 Automotive 6S Battery Monitor
Texas Instruments BQ756506-Q1 Automotive 6S Battery Monitor
Texas Instruments BQ756506-Q1 automotive 6S precision battery monitor provides high-precision battery voltage measurement of up to 6S battery modules. The device can provide the above measurement within 200 µ s, and also supports shunt resistor current detection measurement. With the help of integrated front-end filter, a simple, low rated voltage differential RC filter can be used on the battery input channel to realize the system. In addition, the integrated rear ADC low-pass filter can perform filtered, DC like voltage measurements.
TI BQ756506-Q1 automotive 6S battery monitor supports integrated current detection function and can be synchronized with battery voltage measurement to better calculate the State of Charge (SOC).
The device also supports the integrated current detection function, which can be synchronized with the battery voltage measurement to better calculate the State of Charge (SOC). BQ756506-Q1 supports independent internal battery balance, and automatically pauses and restores balance by monitoring temperature to avoid overheating conditions.
