Микросхемы и комплектующие ISL94216IRZ

Battery Supervisor & Monitor , 1 Wire/I2C/SPI, 12V to 55V, QFN-EP, 64 Pin

16-cell battery front end (BFE) IC in 64 lead QFN package. It is 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 allows for accurate monitoring of cell voltage, temperature and load current for management of the overall state of the battery pack 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 ISL94216 features internal cell balancing circuitry that provides 8mA of balance current per cell. Typical applications include light electric vehicles such as e-bikes, e-scooters, and e-motorcycles, cordless power and gardening tools, home appliances, portable battery packs (24V, 36V, 42V, and 48V), telecom and server farms, solar farms and energy storage systems.
