The PW5200A/ PW5200C is high efficiency synchronous, PWM step-up DC/DC converters optimizedto provide a high efficient solution to medium power systems. The devices work with a 1.4MHz fixedfrequency switching. These features minimize overall solution footprint by allowing the use of tiny,low profile inductors and ceramic capacitors. Automatic PWM/PFM mode switching at light loadsaves power and improves efficiency

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

The PW4554 is a cost-effective, fully integrated high input voltage single-cell Li-ion battery charger.The charger uses a CC/CV charge profile required by Li-ion battery. The charger accepts an inputvoltage up to 24V but is disabled when the input voltage exceeds the OVP threshold, typically 6.8V,to prevent excessive power dissipation. The 24V rating eliminates the over-voltage protection circuitrequired in a low input voltage charger

PW4065 是一款完整的單節(jié)鋰電池充電器，帶電池正負(fù)極反接保護(hù)、 輸入電源正負(fù)極反接保護(hù)的芯片，兼容大小 3mA-600mA 充電電流。 PW4065 可以適合 USB 電源和適配器電源工作。由于采用了內(nèi)部 PMOSFET 架構(gòu)，加上防倒充電路，所以不需要外部檢測電阻器和隔離二極管。熱反饋可對充電電流進(jìn)行自動調(diào)節(jié)，以便在大功率操作或高環(huán)境溫度條件下對芯片溫度加以限制。充滿電壓可分為兩檔： 4.35V、 4.2V。充電電流可通過一個電阻器進(jìn)行外部設(shè)置。當(dāng)電池達(dá)到預(yù)設(shè)電壓之后，充電電流降至設(shè)定值 1/10， PW4065 將自動終止充電。當(dāng)輸入電壓（交流適配器或 USB 電源）被拿掉時， PW4065 自動進(jìn)入一個低電流狀態(tài)，電池漏電流在 1μA 以下。 PW4065 的其他特點包括電源自適應(yīng)、 欠壓閉鎖、自動再充電和一個用于指示充電狀態(tài)的引腳。PW4065 采用 SOT23-5L 封裝配合較少的外圍原件使其非常適用于便攜式產(chǎn)品

The PW4055 is a complete constant-current /constant-voltage linear charger for single cell lithiumion batteries.Its ThinSOT package and low external component count make the PW4055 ideallysuited for portable applications.Furthermore, the PW4055 is specifically designed to work within USBpower specifications.The PW4055 No external sense resistor is needed, and no blocking diode is required due to theinternal MOSFET architecture.Thermal feedback regulates the charge current to limit the dietemperature during high power operation or high ambient temperature. The charge voltage is fixedat 4.2V, and the charge current can be programmed externally with a single resistor. The PW4055automatically terminates the charge cycle when the charge current drops to 1/10th the programmedvalue after the final float voltage is reached. When the input supply (wall adapter or USB supply) isremoved, the PW4055 automatically enters a low current state, dropping the battery drain currentto less than 2μA. The PW4055 can be put into shutdown mode, reducing the supply current to 25μA.The BAT pin has a 7KV ESD(HBM) capability. Other features include charge current monitor, undervoltage lockout, automatic recharge and a status pin to indicate charge termination and the presenceof an input voltage
