Table 3. Pin description
Description
Switching node of the step-up converter
Power ground pin
Step-up converter output voltage (4.6V)
Not internally connected
Signal ground pin. This pin must be connected to the power ground pin
Voltage reference output. 1µF bypass capacitor must be connected between
this pin and AGND
Negative voltage setting pin. Uses S_WIRE protocol, see details in
Section 6.1.2
Enable control pin. ON=V_INA. When pulled low it puts the device in
shutdown mode
Inverting converter output voltage (Default -4.9V).
Switching node of the inverting converter
Analogic input supply voltage
Power input supply voltage
Internally connected to AGND. Exposed pad must be connected to AGND
and PGND in the PCB layout in order to guarantee proper operation of the
device
