Key features
  • AEC-Q100 qualified
  • Measures 4 to 14 cells in series, with 0 us desynchronization delay between samples. Supports also busbar connection without altering cell results
  • Coulomb counter supporting pack overcurrent detection in both ignition on and off states. Fully synchronized current and voltage samples
  • 16-bit voltage measurement with maximum error of ±2 mV in the [1.7 – 4.7] V range, in whole operating temp range
  • 2.66 Mbps isolated serial communication with regenerative buffer, supporting dual access ring. Less than 2 µs latency between start of conversion of the 1st and the 15th device in a chain. Less than 4 ms to convert and read 96 cells in a system using 8 L9963. Supports both transformer and capacitive based isolation
  • 200 mA passive internal balancing current for each cell in both normal and silent-balancing mode. Possibility of executing cyclic wake-up measurements. Manual/Timed balancing, on multiple channels simultaneously; Internal/external balancing
  • Fully redundant cell measurement path, with ADC Swap, for enhanced safety and limp home functionality
  • Intelligent diagnostic routine providing automatic failure validation. Redundant fault notification through both SPI Global Status Word (GSW) and dedicated FAULT line
  • Two 5 V regulators supporting external load connection with 25 mA (VCOM) and 50 mA (VTREF) current capability
  • 9 GPIOs, with up to 7 analog inputs for NTC sensing
  • Robust hot-plug performance. No Zeners needed in parallel to each cell
  • Full ISO26262 compliant, ASIL-D systems ready
  • TQFP64EP package
