Due to their high energy density, high output voltage, and long cycle life, there is a growing demand for intelligent Li-ion rechargeable batteries in notebook PCs, tablets, smartphones, and other portable electronics. In these applications, accurate charge measurement is essential to limiting charging stresses and maintaining battery health during rapid charging.
The application note introduced today discusses the characteristics required of current sense resistors to ensure accurate and repeatable battery charging levels, and how WSL Power Metal Strip devices deliver these specifications to enable precise and stable current measurement across the entire temperature and power range.
