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 – 11mA will force a logic ‘0’ at the output, while currents higher than -6mA will result in a logic ‘1’ at the output.

FEATURES

► Supply voltage range VS 5.25 to 25V

► Supply voltage range VDD 4.75 to 5.25V

► Maximum overvoltage protection up to 40V

► Low standby current (typical IS = 13µA)

► Contact status monitoring by comparison of the switch resistance with internal reference

► Inputs are current limited

► High noise immunity

► Overtemperatur protected

► – 40°C to + 125 ºC operating temperature

► SO20w package

APPLICATION

► Automotive electronics

► Monitor for Hall Sensors

► Monitor for mechanical switches
