PIN FUNCTIONS
For detailed information on how to set the I MAX pin resistor
value, please see the Operation section.
The I MAX pin requires a 10nF decoupling capacitor to
ground. If not used, tie I MAX to GND.
I MON (Pin 12): Output Current Monitor. This pin is the
collector of a PNP current mirror that outputs 1/100 th
of the power PNP current. When OUT = I MON , the pin
current exactly equals 1/100 th that of the output current.
For detailed information on how to calculate the output
current from the I MON pin, please see the Operation section.
The I MON pin requires a small (22nF minimum) external
decoupling capacitor. If the I MON pin is not used, it must
be tied to GND.
