VNI8200XP Pin connection
14 VREF Analog output
Internally generated DC-DC voltage reference (To be
connected to external 10 nF capacitor).
15 ROW0 Open drain output Status channel 1-2
16 ROW1 Open drain output Status channel 3-4
17 ROW2 Open drain output Status channel 5-6
18 ROW3 Open drain output Status channel 7-8
19 PG Open drain output Power Good diagnostic - active low
20 FAULT
Open drain output Fault indication - active low
21 TWARN Open drain output IC case warning temperature detection - active low
22 FB Analog input
Step-down feedback input. Connecting the output
voltage directly to this pin results in an output voltage
of 3.3 V. An external resistor divider is required for
higher output voltages.
23 GND Ground
24 PHASE Power output Step-down output
25 BOOT Power output
Step-down bootstrap voltage. Used to provide a drive
voltage, higher than the supply voltage, to power the
switch of the step-down regulator.
26 NC Not connected
27 OUT8 Power output Channel 8 power output
28 OUT7 Power output Channel 7 power output
29 OUT6 Power output Channel 6 power output
30 OUT5 Power output Channel 5 power output
31 OUT4 Power output Channel 4 power output
32 OUT3 Power output Channel 3 power output
33 OUT2 Power output Channel 2 power output
34 OUT1 Power output Channel 1 power output
35 NC Not connected
36 NC Not connected
