The ISL94216A is a 16-cell battery front-end (BFE) IC, an essential component of any battery management system (BMS), which periodically scans battery status and the operating environment to optimize battery life and prevent catastrophic failures. A differential multiplexer and 16-bit ADC allow for accurate monitoring of cell voltage, temperature, and load current for management of the overall state of the battery pack. The ISL94216A supports I²C, SPI, and single-wire protocols, allowing customers to connect an MCU in a proprietary battery management solution. Low current consumption with an average IDLE mode current of 200µA and a SHIP mode current of less than 18µA maximizes the storage and discharge life of a battery pack. The ISL94216A features internal cell balancing circuitry that provides 8mA of balance current per cell. External cell balancing for higher currents is also supported. This 16-cell high-voltage BFE IC is offered in an efficient 64 Ld QFN package with a thermal pad.
