Table 5-1 Pin Functions
PIN TYPE(1) RESET Description
NAME NO.
ADCIN1 2 I Hi-Z Configuration input. Connect to a resistor divider to LDO_3V3.
ADCIN2 3 I Hi-Z Configuration input. Connect to a resistor divider to LDO_3V3.
CC1 24 I/O Hi-Z I/O for USB Type-C .
CC2 25 I/O Hi-Z I/O for USB Type-C .
CHG_HI 17 I Hi-Z Charge logic input to select between minimum or maximum Type-C current advertisement.
CTL 30 I Hi-Z This pin controls which BC 1.2 mode is used. Pull to GND for CDP mode. Pull high for DCP mode.
DEBUG 6 O Hi-Z Open-drain logic output that is asserted low when a Type-C debug accessory is detected.
EN 5 I Low When this pin is pulled low or left floating, the device will be disabled and remain in the Type-C Error Recovery state.
FAULT 7 O Hi-Z Open-drain logic output that asserts when an over-current fault is detected.
GND 11,12,14,15,16,19,20 — — Ground. Connect to ground plane.
