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 CC Power-Supply Input. Bypass V CC 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.
