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

Configurable Reset Output
Four-State SMBus Address. Address sampled upon POR. Connect A0 to ground, DBP,
SCL, or SDA to program an individual address when connecting multiple devices. See
the I²C/SMBus-Compatible Serial Interface section.

Ground. Connect all GND connections together.
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
configure GPIO5 and GPIO6. See the General-Purpose Inputs/Outputs section.
Analog Enable Input. Apply a voltage greater than the 0.525V (typ) threshold to enable
all outputs. The power-down sequence is triggered when EN falls below 0.5V (typ) and
all outputs are deasserted.

DAC Outputs. DACOUT1–DACOUT8 are the outputs of an internal 8-bit DAC. Set
DACOUT1–DACOUT8 ranges through configuration registers. Connect a DACOUT_ to
an external DC-DC converter for margining. Leave DACOUT_ outputs unconnected, if
unused.
DAC Outputs. DACOUT9–DACOUT12 are the outputs of an internal 8-bit DAC. Set

DACOUT9– DACOUT9–DACOUT12 ranges through configuration registers. Connect a DACOUT_ to
DACOUT12 an external DC-DC converter for margining. Leave DACOUT_ outputs unconnected, if
unused.
