PJ3002SE
USB Charging Controller
Description
The PJ3002SE is the USB decated charging port controller IC. The IC is used to facilitate charging procedure when
most of the mainstream handheld devices are detected. The PJ3002SE is suitable for all the charger products using
USB interface like power bank, wall adapter and even MID device with OTG function. The IC is provided with enhanced
ESD protection up to +/-8kV with application on D+/D- Pins.
