Renesas Electronics Corporation introduced a new family of multi-cell full battery front end (BFE) ICs for battery management systems (BMS) built for the larger, high-voltage battery packs that power e-scooters, energy storage, high-voltage power tools, and other high-voltage equipment. The new ICs provide fast, flexible, cell balancing up to 200 mA+, a critical function to enable fast recharging and high utilization in large battery packs with hot plug tolerance up to 62V. Designed for higher voltage mobility applications where larger cell count and temperature variance across cells are more likely to lead to cell-to-cell imbalances, the RAA489206 provides full high-side battery protection and monitoring for 4S to 16S cell battery packs. The RAA489204 provides improved daisy chain operation with accelerated device-to-device communication and enhanced diagnostics compared with previous-generation devices, as well as internal cell balancing options and support for the higher voltages and cell count required by UPS systems, grid backup, and other energy storage systems. The new ICs? high integration simplifies the design cycle and reduces customers? system BOM costs significantly, accelerating design and BOM selection time from months to weeks. The ICs also feature extensive built-in self diagnostics, improving their safety functionality, reducing firmware workload, and easing the design burden for meeting safety standards. Pin-to-pin compatibility with Renesas? previous BFE devices simplifies the design cycle even further, offering customers a quick and seamless migration path to the new BFE ICs. Key Features of the RAA489206: 16 cell voltage measurements. Internal (10 mA) and external (200 mA) cell balancing options. Operating voltage range of between 12V and 55V with +/- 10mV voltage measurement accuracy. Up to 20 cm2 board space reduction. Low-side current sense measurement. High-side charge/discharge FET battery protection. Key Features of the RAA489204: Operating voltage range of between 10V and 65V with +/- 10mV voltage measurement accuracy and +/-190mV pack voltage measurement accuracy Measures and performs read-back on all voltages, temperatures, and diagnostics for 112 cells in less than 10ms. Cell balancing with both internal and external FETs supported. Up to 6 external thermistor inputs. Robust, low-power (typically 1mA when transmitting 10% of time) daisy chain communications. Stackable up to 30 ICs.
