Mingarda Electronics (Supply & Demand) ISL78714ANZ: Automotive grade multi-segment lithium-ion battery manager IC 64-TQFP

Overview:

The ISL78714 Automotive-grade lithium-ion Battery Manager IC monitors up to 14 batteries in series and is optimized to meet stringent automotive performance, reliability and safety requirements. The device provides all the functions of such critical components in a battery management system, such as accurate battery voltage and temperature monitoring, battery balancing, and extensive system diagnostics.

In a typical configuration, the main ISL78714 communicates with the host microcontroller via the SPI port and up to 29 additional ISL78714 devices are connected together via a reliable dedicated dual-wire Daisy chain. This communication system is very flexible and can be implemented with capacitor isolation, transformer isolation or a combination of both.

There are three battery balance modes: manual balance mode, timed balance mode and automatic balance mode. The auto balance mode terminates the balance after the host's specified amount of power is consumed from each battery.
