Rev. 0.4 : PA Thermistor Pull up
BB_CLK has special layout and component requirements.
GND_REF must connect directly to cap on a thin trace
The cap should via directly to main ground with
no connections to intermediate ground fills

5/10/15mA sink
5/10/15mA sink
40mA sink
AMUX Input
Rev_0.6
< 4-1-3-1_PMIC_PM8926_DATA >
2. We recommend Ceramic Cap.
MC-C06162-1 : 1. Do not connect negative of tantal Cap. to positive voltage if use
(DGMS Guide)
REV.0.6
Routing Width 2mm
<9-1-2_Battery_CNT_4P>
Use F(1%) grade component
1. PCB rev
2. Device ADC
3. Thermistor, temperature pheri.
MC-C04766-5 :
(DGMS Guide)
(DGMS Guide)
MC-C00073-15 : Apply to large capacity around the bat connector
1. Over 47uF around the bat connector
2. Over 100uF totally on Vbat line
Use the TVS diode of VR=5V, when TVS diode have to use for ESD
External sensing resistor : ERHY0035601(10mm ohm, 1%)
If you use external sensing resister, you have to change 0ohm to Sensing Resister
