ADBMS6830BCSWZ-RL

ADBMS6830BCSWZ-RL is a multicell battery stack monitor that measures up to 16 series-connected battery cells with a lifetime total measurement error (TME) of less than 2mV over the full temperature range. The measurement input range of -2V to +5.5V makes the device suitable for most battery chemistries and allows the measurement of voltages across bus bars. Provisions are made for bypassing bus bars without dedicating any measurement channels. All cells can be measured simultaneously and redundantly with two individual analogue-to-digital converters (ADCs). The continuously operating ADCs with a high sampling rate of 4.096MHz allow reduced external analogue filtering and aliasing-free measurement results. Higher noise reduction can be achieved by subsequent programmable infinite impulse response (IIR) filters. It is used in applications such as backup battery systems, grid energy storage, battery cell and pack management.

• Measures up to 16 battery cells in series, simultaneous and continuous measurement of cell voltages
• Configurable integrated low-pass filtering, stackable architecture for high-voltage battery packs
• 2Mbps isolated serial communications, uses a single twisted pair, up to 20 meters per segment

• Passive cell balancing up to 300mA per channel with programmable PWM
• Temperature or other sensor inputs, configurable as an I²C or SPI
• LPCM for cell and temperature monitoring in key-off state, provisions for bus bars
• Measurement resolution is 0.15mV/bit typical at (TJ = -40°C to +125°C)
• ADC transition noise is 40μV rms typical at (TJ = -40°C to +125°C)
• Operating temperature range from -40°C to +125°C, 8-lead LQFP-EP package
