具电流限制理想二极管和电压 / 电流 (V/I) 监视器的线性超级电容器充电器

LTC®4425 是一款恒定电流/恒定电压线性充电器，专为从一个锂离子/锂聚合物电池、一个 USB 端口或一个 2.7V 至 5.5V 电流限制电源对一个两节超级电容器电池组进行充电而设计。该器件起一个理想二极管的作用，并具有一个极低的 50mΩ 接通电阻，从而使其成为高峰值功率/低平均功率应用的合适之选。LTC4425 能够以一个恒定充电电流将输出电容器充电至一个外部设置的输出电压 (在 LDO 模式中)，或者运用一种智能充电电流模式将输出电容器充电至 VIN (在标准模式中) 以限制浪涌电流，直到 VIN 至 VOUT 之差少于 250mV 为止。此外，也可把 LTC4425 设定以将输出 • 50mΩ 理想二极管 (从 VIN 至 VOUT) \n\n• 智能充电电流模式可限制浪涌电流 \n\n• 内部电池平衡器 (无外部电阻器) \n\n• 可编程输出电压 (LDO 模式) \n\n• 可编程 VIN 至 VOUT 电流限值 \n\n• 可通过 PROG 引脚连续监视 VIN 至 VOUT 电流 \n\n• 低静态电流：20μA \n\n• VIN 电源故障、PGOOD 指示器 \n\n• 2.45V/2.7V 电池保护分路 (4.9V/5.4V 超级电容器最大 Top-Off 电压) \n\n• 3A 峰值电流限值，热限制 \n\n• 纤巧型应用电路，3mm x 3mm x;
