Product Overview
ADBMS6948WCCSZ is a 16-channel, battery pack monitoring system. This is a multi-cell battery monitor with the industry's first parallel measurement architecture, which measures up to 16 series-connected battery cells with a TME of less than 3mV over the full temperature range and lifetime. The parallel measurement architecture ensures the lowest external component cost in its category. It is the industry's only battery management system with redundancy on voltage, current, temperature, and overcurrent detection. The ADBMS6948 also provides the best-in-class integrated bidirectional current measurement capability. It measures the current flowing in and out of the battery module by measuring the voltage drop over an external sense resistor with an input offset voltage of 1µV and 0.1% gain error over a lifetime. Typical applications include mild hybrid electric vehicles, 2-wheeler and 3-wheeler electric vehicles 4-wheeler electric vehicle auxiliary battery, backup battery systems and ESS.
- Cell voltage measurement: passive cell balancing up to 300mA per cell
- Pack current measurement: 1µV/bit resolution, ±131mV dynamic range, 1µV over the lifetime offset
- Dedicated charge measurement/coulomb counter and 0.1% over the lifetime gain error
- Synchronous pack current and cell voltage measurements
- Short/over current detection,
2 µs response time, programmable detection time and threshold - Dedicated outputs for MOSFET/contactor control and redundant measurement, algorithm, fault pin
- 10 GPIO channels, low power monitoring for key-off state
- 4-wire SPI 4MHz communication interface
- AEC-Q100 qualified for automotive application
- 64 pin QFN-SS package and temperature range from -40 to 125°C
