1) All p ower traces s hould be routed on the outer la yers
GNDP, VAD, VSYS, LX, VCHG, VBATT
2) Use Kelvin connec tions for R3, R4
(sepe rate f orce and meas urement tr aces)
3) R23 and R24 are d ummy r esistors, f or layout pur poses only
(ser ves as single point connec tion b etween GNDP & GNDA)
4) Foo tprint TO-236 is equivalent to SOT-23
5) Foo tprint SIP/1P is a single hole axial pad
6) All r esisitors, capa citor s and semiconductor s are SMD
7) Pote ntiometer s, and test poin ts are axial devices
