AN_SY68920 3 to 6 Series Cell Battery Monitor, Balance, Protection For Li-ion and Phosphate Application Preliminary Specification General Description Features The SY68920 is the analog front-end (AFE) device for 3-6 series cell battery. The device consists of battery monitor (cell voltage, pack current, pack temperature), cell balance and pack low-side protection, which can cover OCD, SCD, OV, UV, and detection of an external secondary protector fault. The SY68920 can support both internal and external cell balance strategy. Sub-blocks can be enabled or disabled to control the whole current consumption. When the device is not activated, it offers an extremely low consumption in SHIP mode. Host can access all the information of battery pack by I2C interface for management purpose. SY68920 along with small QFN5×5 footprint provides small PCB area application.  Internal ADC Measures Cell Voltage, Pack or Die Temperature  A Separate, Internal ADC Measures Pack Current  Low-Side Charge and Discharge NCH FET Drivers  Over Current Protection during Discharge (OCD)  Short-Circuit Protection during Discharge (SCD)  Cell Over Voltage Protection (OV)  Cell Under Voltage Protection (UV)  Secondary Protector Fault Detection  Integrated Cell Balance FETs  Integrated Internal Cell Balance Strategy  Alert Interrupt for Host  3.3V External Regulator  Simple I2C Compatible Interface  Low Profile QFN5×5 Package Ordering Information Applications  Light Electric Vehicles (LEV)  Power Tools and Garden Tools  Energy Storage Systems (ESS) SY68920 □(□□ □) Package Code Optional Spec Code Ordering Number SY68920QEQ Package type QFN5×5-32 Note Typical Application PACK+ RBAT CELL6 CELL5 RVC6 RVC5 CELL4 RVC4 CELL3 RVC3 CELL2 RVC2 RVC1 CELL1 RVC0 VC6 BAT CVC6 VC5 VCC CVC5 VC4 CVC4 CVC3 CVC2 CVC1 SY68920 CBAT VDD CCAP1 CVCC CVDD VC3 CAP1 VC2 SCL VCC VC1 SDA SCL VC0 TS1 SRP GND Micro SDA Controller GPIO SRN CHG ALERT DSG RTS1 PUSH-BUTTON FOR BOOT GND CVC0 RSNS QDSG QCHG PACK- Figure1.
