General-Purpose Input/Output 7 and General-Purpose Input/Output 8.
GPIO_s can be configured to act as a TTL input, a push-pull, open-drain, or
high-impedance output or a pulldown circuit during a fault event or reverse
sequencing.
GPIO1–GPIO6
General-Purpose Input/Output 1–General-Purpose Input/Output 6. GPIO_s
can be configured to act as a TTL input, a push-pull, open-drain, or high-
impedance output or a pulldown circuit during a fault event.
N.C.
No Connection. Not internally connected.

Analog Enable Input. All outputs deassert when VEN is below the enable
threshold.
Digital Bypass. All push-pull outputs are referenced to DBP. Bypass DBP with
a 1FF capacitor to GND.
Device Power Supply. Connect VCC to a voltage from 2.8V to 14V. Bypass
VCC with a 10FF capacitor to GND.
Analog Bypass. Bypass ABP with a 1FF ceramic capacitor to GND.
Monitor Voltage Input 9–Monitor Voltage Input 12. Set monitor voltage range
through configuration registers. Measured value written to the ADC register
can be read back through the SMBus or JTAG interface.
Exposed Pad. Internally connected to GND. Connect to ground, but do not
use as the main ground connection.
