8.1 ESD protection

For the HBCC package, the pins that are connected to the USB connector (DP, DM,

VCC(5V0) and GND) have a minimum of ±12 kV ESD protection. The ±12 kV measurement

is limited by the test equipment. Capacitors of 4.7 µF connected from VREG3V3 to GND

and VCC(5V0) to GND are required to achieve this ±12 kV ESD protection (see Figure 4).
