PCB Layout notes
V_BAT
1) All pow er traces should be routed on the outer layers
GNDP, VAD, VSYS, LX, VCHG, VBATT
2) Use Kelvin connections for R3, R4
(seperate force and measurement traces)
3) R23 and R24 are dummy resistors, for layout purposes only
(serves as single point connection 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
