PIN NAME FUNCTION

1 RS-4 Ground Reference for ADC4 Voltage Measurement

2, 21, 36 V

Digital-Supply Return Node (Ground)

3 RS+4 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 V

Supply Voltage. Bypass V

to V

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

RST

Reset Active-Low Input

14 MSDA Master I

C Data Input/Output. Open-drain output.

15 MSCL Master I

C 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.
