Comments / Signal routing
D1
Reverse battery protection
C1
Bulk Capacitor
C2
100 nF, SMD Ceramic
Close (<5.0 mm) to VSUP1, VSUP2 pins with good ground return
C3
100 nF, SMD Ceramic
Close (<3.0 mm) to digital supply pins (EVDD, EVSS) with good
ground return.
The positive analog (VREFH, VDDA) and the digital (EVDD) supply
should be connected right at the C3.
C4
4.7
μF, SMD Ceramic or Low ESR
Bulk Capacitor
C5
180 pF, SMD Ceramic
Close (<5.0 mm) to LIN pin.
Total Capacitance per LIN node has to be below 220 pF.
(CTOTAL = CLIN-PIN + C5 + CVARISTOR ~ 10 pF + 180 pF + 15 pF)
Varistor Type TDK AVR-M1608C270MBAAB
Optional (close to LIN connector)
SMD Ferrite Bead Type TDK MMZ2012Y202B
Optional, (close to LIN connector)
