GENERAL DESCRIPTION


The BCT2601 is a battery charger and power path management device with integrated converter and power switches use with 1-cell Li-Ion, Li-polymer batteries. It is capable for fast charging and supports a wide input voltage range suitable for smart phones, tablets and portable systems.

The BCT2601 includes four main power switches: input reverse blocking FET (RBFET, Q1), high-side switching FET for buck or boost mode (HSFET, Q2), low-side switching FET for buck or boost mode switching (LSFET, Q3) and battery FET (BATFET, Q4).

The BCT2601 is USB 2.0 and USB 3.0 power specifications compliant with input current and voltage regulation. It also meets USB On-The-Go (OTG) power rating specification.

The BCT2601 system voltage is regulated slightly above the battery voltage by the power path management circuit and is kept above the programmable minimum system voltage (3.5V by default). Therefore, system power is maintained even if the battery is completely depleted or removed.

The BCT2601, available in QFN-4×4-24L package, provide a very compact system solution external components and PCB area.

概要

BCT4056是一款完整的单节锂离子电池恒压恒流充电管理芯片。采用带有散热PAD的SOP8封装形式，外加很少的外部原件，使其成为便携应用的理想选择。通常可应用在USB电源或适配器电源中。

BCT4056不需要电流检测电阻，也不需要外部隔离二极管实现防倒灌应用。其内部有热反馈电路可以对在充电过程中对芯片温度加以控制。充电截止电压固定在 4.2V/4.35V, 充电电流可以外接电阻调节，当充电电流达到恒流电流的1/10时最小10mA， BCT4056将终止充电。当输入电压（适配器或 USB）被拿掉后，BCT4056进入睡眠模式。芯片内部自动 关断充电通路，输入电压变低。此时电池漏电流降低到2uA 以下。当BCT4056有电源而电池拿掉时，芯片电流为降低至55uA，来降低系统损耗。

BCT4056 还具有电池温度检测，输入欠压锁定，自动再充电和两个充电指示引脚。

GENERAL DESCRIPTION

The BCT1813 is a high efficiency, high frequency synchronous DC-DC step-down converter. The 100% duty cycle feature provides low dropout operation, extending battery life in portable systems.

The internal synchronous switch increases efficiency and eliminates the need for external Schottky diode. At shutdown mode, the input supply current is less than 1µA.

The current limit protection and on-chip thermal shutdown features provide protection against any combination of overload or ambient temperature.

The BCT1813 is available in a 6-pin SOT23-6 package, which provides a compact solution with minimal external components.

600mA, 1.2MHz, 42V Synchronous Buck Converter" ["thumb"] => NULL ["keywords"] => NULL ["description"] => NULL ["content"] => string(5209) "
GENERAL DESCRIPTION

The BCT1451 is a high frequency, synchronous Buck converter with integrated switches. It can deliver up to 600mA to the output over a wide input voltage range of 5V to 42V. It is suitable for various industrial or automotive applications with high input voltage or for power conditioning from unregulated sources. Moreover, the low 14µA quiescent current and ultra-low shutdown current of only 0.6µA make it a suitable choice for battery-powered applications.

BCT1451 features high efficiency over a wide load range achieved by scaling down the switching frequency at light loads to reduce switching and gate driving losses. Other features include internal compensation, internal monotonic soft-start even with pre-biased output and fast loop response thanks to the peak- current mode controller. Switching at 1.2MHz, the BCT1451 can prevent EMI noise problems, such as the ones found in AM radio, ADSL and PLC applications.

Protection features include current limiting and short- circuit protection, thermal shutdown with auto recovery and output over-voltage protection. Frequency fold-back helps prevent inductor current runaway during startup. 

BCT1451 is available in a Green SOT23-6 package.
