8.1 ESD protection

For HBCC package, the pins that are connected to the USB connector (D+, D−,

VCC(5.0) 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

Vreg(3.3) to GND and VCC(5.0) to GND are required to achieve this ±12 kV ESD

protection (see Figure 4).

The ISP1102W can withstand ±12 kV using the Human Body Model and ±5 kV using

the Contact Discharge Method as specified in IEC 61000-4-2.
