The PW4556 series of devices are highly integrated Li-Ion and Li-Pol linear chargers targetedat small capacity battery for portable applications. It is a complete constant-current/ constantvoltage linear charger. No external sense resistor is needed, and no blocking diode is required dueto the internal MOSFET architecture. It can deliver up to 300mA of charge current (using a goodthermal PCB layout) with a final float voltage accuracy of ±1%. The charge voltage is fixed at 4.2V or4.35V, and the charge current can be programmed externally with a single resistor. The chargerfunction has high accuracy current and voltage regulation loops and charge termination

PW4065 是一款完整的单节锂电池充电器,带电池正负极反接保护、 输入电源正负极反接保护的芯片,兼容大小 3mA-600mA 充电电流。 PW4065 可以适合 USB 电源和适配器电源工作。由于采用了内部 PMOSFET 架构,加上防倒充电路,所以不需要外部检测电阻器和隔离二极管。热反馈可对充电电流进行自动调节,以便在大功率操作或高环境温度条件下对芯片温度加以限制。充满电压可分为两档: 4.35V、 4.2V。充电电流可通过一个电阻器进行外部设置。当电池达到预设电压之后,充电电流降至设定值 1/10, PW4065 将自动终止充电。当输入电压(交流适配器或 USB 电源)被拿掉时, PW4065 自动进入一个低电流状态,电池漏电流在 1μA 以下。 PW4065 的其他特点包括电源自适应、 欠压闭锁、自动再充电和一个用于指示充电状态的引脚。PW4065 采用 SOT23-5L 封装配合较少的外围原件使其非常适用于便携式产品

PW4054 是一款性能优异的单节锂离子电池恒流/恒压线性充电器。PW4054 适合给 USB 电源以及适配器电源供电。基于特殊的内部 MOSFET 架构以及防倒充电路, PW4054 不需要外接检测电阻和隔离二极管。当外部环境温度过高或者在大功率应用时,热反馈可以调节充电电流以降低芯片温度。充电电压固定在 4.2V,而充电电流则可以通过一个电阻器进行外部设置。当充电电流在达到最终浮充电压之后降至设定值的 1/10,芯片将终止充电循环。当输入电压断开时, PW4054 进入睡眠状态,电池漏电流将降到 1uA 以下。 PW4054 还可以被设置于停机模式,此时芯片静态电流降至 25uA。PW4054 还包括其他特性:欠压锁定,自动再充电和充电状态标志。PW4054 采用 SOT23-5L 封装配合较少的外围原件使其非常适用于便携式产品

PW2330 develops a high efficiency synchronous step down DC-DC converter capable of delivering3A output current. PW2330 operates over a wide input voltage range from 4.5V to 30V andintegrates main switch and synchronous switch with very low RDS(ON) to minimize the conductionloss. PW2330 adopts the proprietary instant PWM architecture to achieve fast transient responsesfor high step down applications and high efficiency at light loads. In addition, it operates atpseudo-constant frequency of 500kHz under continuous conduction mode to minimize the size ofinductor and capacitor
