MON1–
MON8
ADC Monitored Voltage Inputs. Set ADC input range for each IN_ through
configuration registers. Measured values are written to ADC registers and can be
read back through the I²C or JTAG interface.

No Connection. Must leave unconnected.
RESET Configurable Reset Output
Four-State SMBus Address. Address sampled upon POR. Connect A0 to ground,

General-Purpose Input/Output. GPIO6 and GPIO5 are configurable as open-drain or
push-pull outputs, dedicated fault outputs, or for watchdog functionality. GPIO5 is
configurable as a watchdog input (WDI). GPIO6 is configurable as a watchdog
output (WDO). These inputs/outputs are also configurable for margining. Use the
EEPROM to GPIO5 and GPIO6. See the General-Purpose Inputs/Outputs section.
Analog Enable Input. Apply a voltage greater than the 0.525V (typ) threshold to
EN
enable all outputs. Power-down sequence triggered when EN falls below 0.5V (typ)
and all outputs are deasserted.
DACOUT1–
DACOUT8
DACOUT9–
DACOUT12
DAC Outputs. DACOUT1–DACOUT8 are the outputs of an internal 8-bit DAC. Set
DACOUT_ ranges through configuration registers. Connect a DACOUT_ to an
external DC-DC converter for margining. Leave DACOUT_ outputs unconnected, if
unused.
