WKUPR

Wake-up Upper Device Signal (ISL9216 only). This output wakes up the ISL9217 (upper device) when the output is turned on by the

microcontroller. Once the upper device is awake, this output can be turned off.

SDA

Serial Data (ISL9216 only). This is the bi-directional data line for an I2C interface.

SCL

Serial Clock. This is the clock line for an I2C communication link.

SDAI

Serial Data Input (ISL9217 only). This pin is a uni-directional I2C serial data input from the ISL9216 to the cascaded ISL9217 device.

This pin connects to the ISL9216 SDAOHV pin.

SDAO

Serial Data Output (ISL9217 only). This pin is a uni-directional I2C serial data output to the ISL9216 from the cascaded ISL9217

device. This pin connects to the ISL9216 SDAIHV pin.

SDAIHV

Serial Data Input (ISL9216 only). This pin is a uni-directional I2C serial data input from the cascaded ISL9217 device to the ISL9216.

This pin connects to the ISL9217 SDAO pin.

SDAOHV Serial Data Output (ISL9216 only). This pin is a uni-directional serial data output from the ISL9216 to the cascaded ISL9217 device.

This pin connects to the ISL9217 SDAI pin.

SCLHV

Serial Clock Output (ISL9216 only). This pin sends clock pulses from the lower device (ISL9216) to the upper device (ISL9217) for

communication between cascaded devices

HVI2C

HV I2C Reference Voltage (ISL9216 only). This is a reference voltage for the ISL9216 to facilitate the communication link between

cascaded devices. Tie this pin on the ISL9216 to the RGO pin of the ISL9217.
