General-Purpose BMS Communication Gateway and EIS Synchronization Controller
The BMA6002 is a battery management communication gateway and TPL transceiver that bridges SPI or CAN FD with TPL. It features dual isolated TPL ports and a serial interface for external control, enabling daisy-chained BMS communication. The BMI6002 is the gateway tailored for industrial environments.
The BMA6402 is a dual-channel TPL transceiver designed to act as the synchronization controller in EIS-enabled battery management systems. Accurate EIS measurement requires precise synchronization across distinct clock domains, preventing errors in impedance measurements. The BMA6402 uses a Frequency Locking Loop (FLL) to achieve nanosecond-level synchronization across multiple chips and channels. This ensures accurate impedance measurements, regardless of battery size or system scale.
