PIN NAME FUNCTION

16 DBP

Digital Bypass. All push-pull outputs are referenced to DBP. Bypass DBP with a 1FF capacitor to

GND.

17 V

Power-Supply Input. Bypass V

to GND with a 10FF ceramic capacitor.

18 ABP

Analog Bypass. Bypass ABP to GND with a 1FF ceramic capacitor.

20–25

MON1–

MON6

Monitor Voltage Inputs. Set the monitor voltage range through the configuration registers.

Measured values are written to the ADC registers and can be read back through the SMBus or

JTAG interface.

26 RESET Configurable Reset Output

— EP

Exposed Pad. Internally connected to GND. Connect to ground, but do not use EP as the main

ground connection.
