线性充电IC

HP4552是一款完整的采用恒定电流/恒定电压的高压、大电流、单节锂离子电池线性充电IC。最高耐压可达28V，6.8V 自动过压保护，充电电流最大可达1A。输入最低工作电压3.8V，满足客户动态调整输入电压的需求，降低充电功耗，提高整体效率。由于采用了内部 PMOS 架构，加上防反充电路，不需要外部隔离二极管。热反馈可对充电电流进行自动调节，可以在大功率应用或高环境温度条件下对芯片温度加以限制。HP4552提供了4.0V、4.1V、4.15V、4.2V、4.35V、4.4V和4.45V七种浮充电压供客户选择， 充电电流可通过一个电阻进行外部设置。当电池电压达到浮充电压时，充电电流逐渐下降，当充 •  最高输入电压可达28V\n•  6.8V 输入过压保护（OVP）\n•  电池反接保护\n•  无需防倒充MOSFET、检测电阻或隔离二极管\n•  浮充电压精度达到±1% \n•  1C/10 充电终止，自动再充电\n•  软启动，限制浪涌电流\n•  采用SOT23-5L、SOT23-6L、DFN3x3-8L封装;
