This way a single pair of inputs can monitor the voltage
and the current of a power-supply rail. The overvoltage
threshold on the even-numbered MON_ inputs can be
used as an overcurrent flag.
Figure 20 shows how to connect a current-sense resistor
to a pair of MON_ inputs for monitoring both current and
voltage.
For best accuracy, set the voltage range on the even-
numbered MON_ to 1.4V. Since the ADC conversion
results are 10 bits, the monitoring precision is 1.4V/1024
= 1.4mV. For more accurate current measurements, use
larger current-sense resistors. The application require-
ments should determine the balance between accuracy
and voltage drop across the current-sense resistor.
Bypass DBP and ABP each with a 1FF ceramic capacitor
to GND. Bypass V
Avoid routing digital return currents through a sensitive
analog area, such as an analog supply input return path
or ABP’s bypass capacitor ground connection. Use
dedicated analog and digital ground planes. Connect
the capacitors as close as possible to the device.
