        How to select the CHRLDO Resistance of MT6357CRV/MT6357MRV?
[Answer]
        CHRLDO is power supply source for internal charger block and it is a 2.8V shunt regulator
                For MT6765/62+MT6371， R2301为7.5K
                For MT6761+MT6371， R2301为7.5K
                For MT6761+Pulse Charger， 建议R2301为1.5K，R2301计算方式：
                [VBUS(min)-2.8]/R> 220uA
