RGO
Regulated output voltage.
This pin connects to the emitter of an external NPN transistor and works in conjunction with
the RGC pin to provides a regulated 3.3V. The voltage at this pin provides feedback for the regulator and power for
many of the ISL9208 internal circuits as well as providing the 3.3V output voltage for the microcontroller and other
external circuits.
RGC
Regulated output control.
This pin connects to the base of an external NPN transistor and works in conjunction with
the RGO pin to provide a regulated 3.3V. The RGC output provides the control signal for the external transistor to
provide the 3.3V regulated voltage on the RGO pin.
WKUP
Wake up Voltage.
This input wakes up the part when the voltage crosses a turn-on threshold (wake up is edge
triggered). The condition of the pin is reflected in the WKUP bit (The WKUP bit is level sensitive.)
WKPOL bit = ”1”: the device wakes up on the rising edge of the WKUP pin. Also, the WKUP bit is HIGH only when
the WKUP pin voltage > threshold.
WKPOL bit = ”0”, the device wakes up on the falling edge of the WKUP pin. Also, the WKUP bit is HIGH only when
the WKUP pin voltage < threshold.
Serial Data.
This is the bidirectional data line for an I
2
C interface.
Serial Clock.
This is the clock input for an I
2
C communication link.
