FUNCTION
PWM Margin Output #4. High impedance when the margining is disabled. A 100% duty cycle
implies this pin is continuously high.
Power-Supply Enable Output #4. Programmable through MFR_MODE for either active high or active
low and either open drain or CMOS push-pull.
PWM Margin Output #3. High impedance when the margining is disabled. A 100% duty cycle
implies this pin is continuously high.
Regulator for Low-Voltage Digital Circuitry. Bypass REG18 to V SS with 1 F F and 10nF capacitors. Do
not connect other circuitry to this pin.
Power-Supply Enable Output #3. Programmable through MFR_MODE for either active high or active
low and either open drain or CMOS push-pull.
PWM Margin Output #2. High impedance when the margining is disabled. A 100% duty cycle
implies this pin is continuously high.
Power-Supply Enable Output #2. Programmable through MFR_MODE for either active high or active
low and either open drain or CMOS push-pull.
PWM Margin Output #1. High impedance when the margining is disabled. A 100% duty cycle
implies this pin is continuously high.
Power-Supply Enable Output #1. Programmable through MFR_MODE for either active high or active
low and either open drain or CMOS push-pull.
PWM Margin Output #0. High impedance when the margining is disabled. A 100% duty cycle
implies this pin is continuously high.
Regulator for Analog Circuitry. Bypass REG25 to V SS with 30 F F to 47 F F. Do not connect other
circuitry to this pin.
Power-Supply Enable Output #0. Programmable through MFR_MODE for either active high or active
low and either open drain or CMOS push-pull.

SMBus Address 0 Input/Multiplexer Control Output. This dual-function pin is sampled on device
power-up to determine the SMBus address; connect a 100k I resistor from this pin to either V SS or
33
A0/MUXSEL V DD to set the address. After device power-up, this pin becomes an output that acts as voltage/
current selector for an external analog multiplexer. MUXSEL is low for voltage measurements and
high for current measurements.
Active-Low, Open-Drain Fault Input/Output. This pin is asserted when one or more of the power supplies
in a global group are shut down due to a fault condition. Also, this pin is monitored and, when it is

asserted, all power supplies in a global group are shut down. This pin is used to provide hardware
control for power supplies in a global group across multiple devices. This output is unconditionally
deasserted when RST is asserted or the device is power cycled. This pin has a 50 F s deglitch filter.
Device Enable. Option through ON_OFF_CONFIG for active-low or active-high power-supply control.
This pin has a 50 F s deglitch filter.
SMBus Address 1 Input/Power-Good Output. This dual-function pin is sampled on device power-up
to determine the SMBus address; connect a 100k I resistor from this pin to either V SS or V DD to set
the address. After device power-up, this pin becomes an output that transitions high when all the
enabled power supplies are above their associated POWER_GOOD_ON thresholds.
