Power-Supply ADC Voltage-Sense Input, Measurement Relative to RS-4

4

RS-3

Ground Reference for ADC3 Voltage Measurement

5

RS+3

Power-Supply ADC Voltage-Sense Input, Measurement Relative to RS-3

6

RS+0

Power-Supply ADC Voltage-Sense Input, Measurement Relative to RS-0

7

RS-0

Ground Reference for ADC0 Voltage Measurement

8

RS+1

Power-Supply ADC Voltage-Sense Input, Measurement Relative to RS-1

9

VDD

Supply Voltage. Bypass VDD to VSS with a 0.1FF capacitor.

10

RS-1

Ground Reference for ADC1 Voltage Measurement

11

RS+2

Power-Supply ADC Voltage-Sense Input, Measurement Relative to RS-2

12

RS-2

Ground Reference for ADC2 Voltage Measurement

13

RST

Reset Active-Low Input

14

MSDA

Master I2C Data Input/Output. Open-drain output.

15

MSCL

Master I2C Clock Output. Open-drain output.

16

PWM5

PWM Margin Output #5. High impedance when the margining is disabled. A 100% duty cycle

implies this pin is continuously high.

17

PSEN5

Power-Supply Enable Output #5. Programmable through MFR_MODE for either active high or active

low and either open drain or CMOS push-pull.
