Maxim公司的MAX77650/MAX77651是具有三输出单电感多输出(SIMO)和充电器的超低功耗PMIC,为低功耗可穿戴应用提供高度集成的电池充电和电源解决方案.可编程快速充电电流7.5mA-300mA,可编程电池电压33.6V-4.6V,可编程端电流0.375mA-45mA,主要用在蓝牙耳机,健美健康和蔼活动监视器,物联网(IoT)和手持设备.本文介绍了MAX77650主要特性,框图,应用电路以及评估板MAX77650 EV主要特性,电路图,材料清单和PCB设计图.

The MAX77650/MAX77651 provide highly-integrated battery charging and power supply solutions for low-power wearable applications where size and efficiency are critical. Both devices feature a SIMO buck-boost regulator that provides three independently programmable power rails from a single inductor to minimize total solution size. A 150mA LDO provides ripple rejection for audio and other noise-sensitive applications. A highly configurable linear charger supports a wide range of Li+ battery capacities and includes battery temperature monitoring for additional safety (JEITA).
