IP4220CZ6
Dual USB 2.0 integrated ESD protection
7. Characteristics
[1] Pins 1, 3, 4 and 6.
[2] Pins 1, 3, 4 and 6 to ground.
[3] Pin 5 to pin 2.
8. Application information
8.1 Universal serial bus 2.0 protection
The device is optimized to protect, for example, two USB 2.0 ports from ESD. Each device
can protect both USB data lines and the V
BUS
supply line. A typical application is shown in
Figure 1
