Table 3. Pin definitions and functions

Symbol

Function

CP2-

Charge pump pin for capacitor 2, negative side.

CP1+

Charge pump pin for capacitor 1, positive side.

CP1-

Charge pump pin for capacitor 1, negative side.

4VS

Power supply voltage (external reverse protection required).

For EMI reason a ceramic capacitor as close as possible to GND is

recommended.

GND

Ground. Reference potential, connected to slug.

GNDD

Digital ground. Reference potential.

7VCCD

Logic voltage supply 3.3 V/5 V: for this input a ceramic capacitor as

close as possible to GND is recommended.

8VCC

Analog voltage supply 3.3 V/5 V: for this input a ceramic capacitor as

close as possible to GND is recommended.

Enable input. The enable input has a pull-down resistor.
