Figure 46. MT6318 Circuit of MASS 2
To Power on the handset, The Power_On_Off Signal must be Low. The external sense resistor R307 0.2ohm can determine
the charging current. The function equation is : Iconstant = 0.16/R307 = about 800mA. Ipre-charging = 10/R307 = about
50mA. The LDO Bypass capacitors are recommended to use Min X5R grade. Specially The DVDD, AVDD,VMEM and
VCORE must be used 4.7uF, 2012 type.
