Управление зарядом и разрядом батареи

Новая высокочастотная импульсная ИМС для зарядки литий-ионных батарей упрощает поддержание постоянного тока в схемах быстрой зарядки портативных устройств. ИМС ADP2291 представляет собой линейное устройство для зарядки одноэлементных литий-ионных батарей с постоянным током/постоянным напряжением. При помощи небольшого количества внешних компонентов на ее основе можно построить простую и безопасную систему зарядки, работающую от широкого диапазона входных напряжений (от 4.5 В до 12 В). Компонент обеспечивает наилучшую в отрасли погрешность контроля напряжения, которая составляет ±0.4% при 25ºC, ±0.6% в диапазоне от 5ºот 55ºC и ±0.7% в диапазоне от 0º до 85ºC.
