PRODUCTION DATA.
The device has PSEL interface for input current limit setting to interface with USB PHY. It directly takes the USB PHY device output to decide whether the input is USB host or charging port. To implement USB100 in the system, the host can enter HiZ mode by setting EN_HIZ bit after 2 min charging with 500 mA input current limit.
INPUT DETECTION | PSEL PIN | INPUT CURRENT LIMIT (IINLIM) | VBUS_STAT |
---|---|---|---|
USB SDP (USB500) | High | 500mA | 001 |
USB DCP / Adapter | Low | 3.25A | 010 |
