INOVLO
I
Input Overvoltage Protection Pin;
Define an upper voltage threshold and switches OFF the device in case of
overvoltages on the VIN supply. Must not be left open.
20
VFB
I
Voltage Loop Feedback Pin;
VFB is intended to set output protection functions.

IOUTMON
SPI
O
Input current monitor output;
Monitor pin that produces a voltage that is 20 times the voltage V_IN1-IN2.
IINMON will be equal 1V when V_IIN1-V_IIN2=50mV
O
Output current monitor output;
Monitor pin that produces a voltage that is 200mV + 8 times the voltage
V_FBH-FBL. IOUTMON will be equal 1.4V when V_FBH-FBL = 150mV.
