ISL94208 Battery Management ICs

Renesas ISL94208 Battery Management ICs feature an analog front-end with overcurrent protection for multi-cell Li-ion battery packs. These ICs are used with a microcontroller and support battery packs consisting of 4 to 6 cells in series and one or more cells in parallel. Using an internal analog multiplexer, the ISL94208 allows a separate microcontroller with an analog-to-digital converter to monitor each cell voltage plus internal and external temperature. Renesas ISL94208 provides integral overcurrent and short circuit protection circuitry, an internal 3.3V voltage regulator, internal cell balancing switches, and drive circuitry for external FET devices to control pack charge and discharge.
