DESCRIPTION
The L9705 is a bipolar monolithic integrated circuit
for monitoring the status of up to four contacts con-
nected to GND and up to four contacts connected
to the battery. The contact sense input supply the
contact current and perform the contact resistance
comparison function.
At the output the contact status is translated into a
logical LOW level (contact closed) or logical HIGH
level (contact open).
