Use the TVS diode of VR=5V, when TVS diode have to use for ESD
2. Over 100uF totally on Vbat line
1. Over 47uF around the bat connector
MC-C00073-15 : Apply to large capacity around the bat connector

It will be changed the value : 10mohm -> 2mohm
Have to check pin map

tuning point
ILIM : set the maximum input current limit
OTG : PSEL HIGH & OTG HIGH IIN LIMIT 500mA OTG LOW IIN LIMIT 100mA
STAT Low : charge in progress High : complete
PSEL High : USB host source Low : adapter source

should be placed close to the IC
VBUS above 6V : 1uF ; below 6V : 4.7uF
CLOSE TO Battery CONNECTOR
REV.B
Only use line VBAT1 from Battery Connector.
Don't use Board GND
Use line GND From Battery GND Pin#3
