Type

Pin Function

D+

A/D IO

USB D+ channel for BC1.2 and proprietary protocols. Can be

configured as I2C-SCL, UART_TX/UART_RX, and ADC input.

D-

A/D IO

USB D- channel for BC1.2 and proprietary protocols. Can be configured

as I2C-SDA, UART_TX/UART_RX, and ADC input.

VBUS

A IO

VBUS sensing and bleeder connection node to provide another path to

discharge the VBUS capacitor. Can be configured as ADC input.

USBP

D IO

Control signal of the blocking N-MOSFET.

CS-

Negative input of a current-sense amplifier for output current sensing.

CS+

Positive input of a current-sense amplifier for output current sensing.

(Exposed Pad)

GND

Power ground. The exposed pad must be connected to GND and well

soldered to a large PCB copper area for maximum power dissipation.
