技术问答

NISSHINBO（日清纺）推出的NJW4813是内置有升压型开关稳压器的双半桥驱动器。它能把Li-ion 电池、5V 电源升压，并使用2个半桥驱动器来驱动压电马达及压电式扬声器。在升压型开关稳压器部内置的17ms软启动功能能够限制电源接通时的突发电流。双半桥驱动器能对应ch.间的各自独立信号输入，提高了微处理器的控制性。输入频率能高达300kHz，当异常发生时能够输出FAULT信号。

Nisshinbo R5661 Series 1-Cell Li-ion Battery Protection IC with Temperature Protection

The R5661 is one-cell Li-ion / polymer battery protection IC provides overcharge, overdischarge, discharge / charge overcurrent, and temperature detections. One of the features of this device is a high-accuracy detection at overcharge and overcurrent. The supply current after overdischarge detection can be reduced to a minimum by stopping the internal circuits. The small WLCSP package is available.
