Figure 3. Application circuit
Functional Description
V
S
The IC and the external units are powered via the V
S
Pin 4. This pin is connected to the battery via a reverse
battery protection diode. An electrolythic capacitor of
22 F smoothes the voltage and absorbes positive and
negative transients.
OUT1, OUT2
OUTx provides a smoothed, very slowly changing supply
voltage for the external units and monitors the output cur-
rent. During normal operating conditions, the OUTx
voltage is typ. 3 V below V
S
, and changes very slowly
with a varying battery voltage in order to suppress distur-
bances in the data transmission. At low V
S
(5.7 to 8.5 V),
the OUTx voltage is typ. 0.5 V below V
S
. This voltage
difference is reduced in order to ensure sufficient supply
voltage for the external unit between OUTx and
RETURNx. The output current capability is 50 mA. The
internal pull-down current at OUTx is typically 3 mA.
