LAYOUT NOTES
1. Capsense pin should be 10mm dia.
2. No plane or trace under capsense button
in any layer.
3. Hatching around capsense button is needed.
A
4. Capsense button to ground spacing should be 20mil.
A
CYPRESS SEMICONDUCTOR © 2013
5. Hatching Details: Typical hatching for the
ground fill is 25 percent on the top layer (7 mil
line, 45 mil spacing) and 17 percent on the bottom
layer (7 mil line, 70 mil spacing).

Connector
1. Place U4 closer to J2.
2. USB 90 ohm differential pairs should be
routed with ground reference.
NOTE:
3. Add ground vias near the USB differential
vias for Z-Axis reference.
4. VBUS trace width should be minimum 20mil.
1.Load the resistor R46 by default, if temperature sensing
is not required remove R46 and load R47.
2.Place NTC Thermistor R25 in close proximity to
Battery to monitor the Battery Temperature
