PCB Layout notes
1) All pow er traces should be routed on the outer layers
GNDP, VAD, VSYS, LX, VCHG, VBATT
2) Use Kelvin connec tions for R3, R4
(seperate force and meas ur ement traces)
3) R23 and R24 are dummy r es is tor s, f or layout purposes only
(serves as single point c onnection betw een GNDP & GNDA)
4) Footprint TO-236 is equivalent to SOT-23
5) Footprint SIP/1P is a single hole axial pad
6) All resisitors, capacitors and semiconductors are SMD
7) Potentiometers, and test points are axial devices
