Linear LTC4079高效高压线性充电解决方案
Linear公司的LTC4079是低静态电流的高效高压线性充电器,输入电压2.7V-60V,可调电池电压从1.2V到60V,可调充电电流从10mA到250A,适用于大多数电池如锂电池,铅酸或镍锰电池等.主要用在嵌入汽车电子和工业,能量收集充电器,薄膜电池产品和备用电池充电器.本文介绍了LTC4079主要特性,框图,多种电池的典型应用电路以及演示板DC2133主要特性,电路图和材料清单.
The LTCR4079 is a low quiescent current, high voltage linear charger for most battery chemistry types including Li-Ion/Polymer, Lead-Acid or NiMH battery stacks up to 60V. The maximum charge current is adjustable from 10mA to 250mA with an external resistor. The battery charge voltage is set using an external resistor divider.
With an integrated power device, current sensing and reverse current protection, a complete charging solution using the LTC4079 requires very few external components.
Thermal regulation ensures maximum charge current up to the specified limit without the risk of overheating. Charging can be terminated by either C/10 or adjustable timer.
