FODCFG Analog input used for FOD threshold configuration, if RCFGEN
is low.
DTCFG Analog input used for dead-time configuration, if RCFGEN is
low.
LEDCFG Analog input used for LED configuration, if RCFGEN is low.
Internally generated 3.3V power supply. Connect a 1μF or
higher value ceramic capacitor from VCC33 to VSSA.

5V system power supply. Connect a 1μF or higher value
ceramic capacitor from VSYS to VSSP.
System regulator output. Connect to VSYS directly or through
an external power dissipating resistor.
Switching supply current sense input. Connect to the positive
side of the current sense resistor.
Main power supply. Provides power to the power drivers as
well as voltage feedback path for the switching supply. Connect
a properly sized supply bypass capacitor in parallel with a
0.1μF ceramic capacitor from VP pin to VSS for voltage loop
stabilization. This pin requires good capacitive bypassing to
VSS, so the ceramic capacitor must be connected with a
shorter than 10mm trace from the pin.
Switching supply controller supply input. Connect a 1μF or
higher value ceramic capacitor, or a 0.1μF ceramic capacitor in
parallel with a 10μF or higher electrolytic capacitor from VHM
to VSSP. This pin requires good capacitive bypassing to VSSP,
so the ceramic capacitor must be connected with a shorter than
10mm trace from the pin.
Switching supply driver output. Connect to the base or gate of
the external power NPN or n-channel MOSFET. See
PAC51xx/52xx User Guide and application notes.
Power ground. Connect to VSS in a star ground configuration.
