Battery Multi-Function Controller IC Lithium Ion/Polymer 32-VFQFPN (5x5) L9961 is part of a complete battery pack monitoring, balancing, and protecting system for Li-Ion and Li-Polymer cells in 3, 4 or 5 series configurations. The L9961 uses a high precision ADC to provide cell voltage, stack voltage and temperature conversion via external NTC. Voltage monitoring functions are cyclically performed with a programmable loop time. Stack current is also monitored via a high accuracy CSA, continuously running and performing also Coulomb counting. Cell balancing is available and can be simultaneously activated on all cells. IC configuration and information exchange for SOC/SOH estimation are performed via I2C peripheral. The IC also integrates a dual pre-driver programmable in both HS/LS configurations for driving pack relays. L9961 also implements battery pack fuse protection to prevent fire and explosion hazards. A 3.3 V regulator with a high current capability is available for supplying pack controller and other external circuitry in both standby and normal operation modes. The IC protects the battery pack against over/under voltage conditions and monitors for over/ under temperature. It also features protection against overcurrent (both directions) and short-circuit in discharge events. Safety-relevant configurations can be stored in the internal NVM to avoid re-programming the device at each wake-up. Features • 2 μA shipment - DEEP SLEEP mode current and 5 μA standby consumption (with VREG LDO active) standby consumption (with VREG LDO active) • Integrated 3.3 V VREG LDO for supplying MCU and LEDs • Measures cell voltage (3 to 5 cells), with over/undervoltage detection and balance undervoltage protection • 12-bit voltage measurement with maximum error of ±15 mV in the [1.5 – 4.5] V range, for -40 °C < TJ < 105 °C • Measures stack voltage, with over/under voltage detection and plausibility check vs. sum of cells • Measures pack temperature via NTC, with over/undertemperature detection • Ratiometric temperature measurement with ±0.8% max. gain error in the [0.2 – VREG] V range, for -40 °C < TJ < 105 °C • Measures battery current, with Coulomb counting, overcurrent (both directions) and short-circuit in discharge protection. • 16-bit signed current measurement with 0.1% full scale error at room temperature • I 2C peripheral for device programming and data transfers over I2C bus • Cell balancing supporting up to 70 mA per cell • Dual configurable HS/LS predriver for pack relay management • Pack fuse management • Embedded NVM for configuration parameters storage • High hotplug robustness Applications • Cordless power tools • Backup energy storage systems and UPS • Light electric vehicles (e-bikes, scooters, etc.) • Portable and semi-portable equipment • Medical equipment #L9961TR #BatteryManagement #BMS #LiIonBattery #LiPoBattery #STMicroelectronics #BatteryProtection #CellBalancing #CoulombCounting #PowerManagement #EmbeddedSystems #EnergyStorage #EBike #PowerTools #ElectronicsDesign
