开关模式锂离子电池充电器

MAX745提供为锂离子电池组充电所需的所有功能。它提供高达4A的调节充电电流且不会变热，电池端子处的调节电压总误差仅为±0.75%。它使用低成本的1%电阻来设置输出电压，并使用低成本的N沟道MOSFET作为电源开关。\n\n MAX745使用两个环路调节电压设定点和充电电流，这两个环路协同工作以在电压和电流调节之间平稳转换。使用标准1%电阻将每节电池的电压调节限值设置在4V至4.4V之间，然后通过引脚绑定将电池数量设置为1到4节。输出电压总误差小于±0.75%。\n\n 对于具有SMBus™微控制器接口并能够为镍镉和镍氢电池充电的类似器件， • 为1至4节锂离子电池充电\n\n• 使用1%电阻时电压调节精度为±0.75%\n\n• 提供高达4A的电流而不会过热\n\n• 90%效率\n\n• 使用低成本设置电阻和N沟道开关\n\n• 高达24V输入\n\n• 最大电池电压高达18V\n\n• 300kHz脉宽调制(PWM)工作模式\n• 低噪音、小型元件\n\n\n\n\n• 独立工作——无需微控制器;
