description
ÿ Supply voltage range VS 5.25 to 25V
The IC is developed for automotive applications. It continuously
ÿ Supply voltage range VDD 4.75 to 5.25V
monitors up to 8 hall sensors or switches to GND.
ÿ Maximum overvoltage protection up to 40V
ÿ Low standby current (typical IS = 13µA)
The input currents are compared to internal references. Currents
ÿ Contact status monitoring by comparison of the
exceeding – 11mA will force a logic ‘0’ at the output, while currents

pinning
higher than -6mA will result in a logic ‘1’ at the output.
ÿ Inputs are current limited
ÿ High noise immunity
If the IC is used to monitor switches, the switch resistance must
ÿ Overtemperatur protected
be higher than 5kÝ for ‘1’ and less than 330Ý for ‘0’ at the out-
ÿ – 40°C to + 125 ºC operating temperature
put.
ÿ SO20w package
The input current as well as the tristate driver are activated with
application
the enable pin. Due to the tristate outputs the IC can be used in
ÿ Automotive electronics
bus configuration.
