APPLICATION
Automotive electronics
Monitor for Hall Sensors
Monitor for mechanical switches
DESCRIPTION
The IC is developed for automotive applications. It continuously
monitors up to
8
hall sensors or switches to GND.
The input currents are compared to internal references. Currents
exceeding –
11
mA will force a logic ‘
0
’ at the output, while currents
higher than -
6
mA will result in a logic ‘
1
’ at the output.
If the IC is used to monitor switches, the switch resistance must
be higher than
5
kY for ‘
1
’ and less than
330
Y for ‘
0
’ at the out-
put.
The input current as well as the tristate driver are activated with
the enable pin. Due to the tristate outputs the IC can be used in
bus configuration.
