Automotive Grade Multi-Cell Li-Ion Battery Manager Development Kit
The ISL78714BMS5XBEKIT1Z is a development kit that facilitates testing of the ISL78714 Li-ion battery pack analog front-end ICs and the Renesas RH850 microcontroller...
The ISL78714 automotive-grade Li-ion battery manager IC supervises up to 14 series connected cells and is optimized to meet stringent automotive performance, reliability, and safety requirements. The device provides all the functions expected of such a critical component in a battery management system, such as accurate cell voltage and temperature monitoring, cell balancing, and extensive system diagnostics. In a typical configuration, a master ISL78714 communicates to a host microcontroller through an SPI port and up to 29 additional ISL78714 devices connected together by a robust, proprietary, two-wire daisy chain. This communication system is highly flexible and can be implemented with capacitor isolation, transformer isolation, or a combination of both. Three cell balancing modes are included: Manual Balance mode, Timed Balance mode, and Auto Balance mode. Auto Balance mode terminates balancing after a host-specified amount of charge has been removed from every cell. The ISL78714 is packaged in a 64-pin TQFP and is specified for operation from -40 °C to +105 °C.
An NDA is required for the full datasheet. Please contact your local Renesas sales representative for more information.

In electric vehicles today, there are two key parameters, the state of health and the state of charge. Renesas' Battery Management Solution (BMS) device supports these parameters. This demonstration highlights Renesas' ISL78714 automotive-grade Li-ion battery manager IC and the RH850/P1M 32-bit automotive microcontroller (MCU). In addition to the ISL78714 battery manager IC and RH850 MCU, the demo board is supported by a host of other Renesas products including the RAA270005 power management IC (PMIC), RV1S2752Q photocoupler, and the uPD166031A/32/33/34 and RAJ2800024/34/44 integrated power devices (IPDs).
