Function
Supply voltage
Circuit ground
Data input for switching the
IRED output current on and off
IR-LED output; when the data
input is high, this output supplies
the IR LED with the constant
current
The resistor at this pin adjusts
the IRED output current
Voltage monitor input of the
internal comparator
Voltage monitor output. This
open collector output is active
when the voltage at MON-I is
below the internal reference
