General Description
L9705 General Description
The L9705 is a bipolar monolithic integrated circuit for monitoring the status of up to four contacts connected 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).
