battery management
battery management is more important than ever as portable applications extend into more industries. The demand for small, low-cost products with long battery life is increasing. Our industry-leading battery management solutions include battery chargers, fuel gauges, battery monitors, battery selectors, and battery
battery management system can be comprised of many functional blocks including: cutoff FETs, a fuel gauge monitor, cell voltage monitor, cell voltage balance, real time clock (RTC), temperature monitors and a state machine. There are many types of battery management ICs available. The grouping of the functional blocks varies widely from a simple analog front end that offers balancing and monitoring and requires a microcontroller (MCU), to a standalone, highly integrated solution that runs autonomously.
