Figure 1. Typical application diagram for the L9705 circuit. The current flowing in the arrow
direction is assumed positive. The external capacitors CIN and COUT represent the total
wiring capacitance at the corresponding pins.
FUNCTIONAL DESCRIPTION
The L9705 circuit monitors the status of the contacts which are connected through the series external re-
sistors RIN to the contact sense input pins. The contacts equivalent circuit is supposed to be as shown in
fig.2 for GND connected contacts (IN 1 to 4) and as shown in fig. 3 for VBAT connected contacts (IN 5 to 8).
Figure 2. The contact sense input connection with the contact equivalent circuit for GND
connected contacts.
Figure 3. The contact sense input connection with the contact equivalent circuit for VBAT
connected contacts.
