DESCRIPTION
The IC is developed for automotive applications. It continuously monitors the status of two groups of switch contacts connected to GND or VBAT.
The input currents are compared to internal references. The IC is designed to operate with an external resistor of 1kÝ.

FEATURES
► Programmable input current of 1mA / 10mA
► 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 < 10µA)
► Contact status monitoring by comparing the switch resistance with the internal reference
► High noise immunity
► – 40°C to + 125 ºC operating temperature
► SO24w package

APPLICATION
► Automotive electronics
► Monitor for mechanical switches
► Monitor for interface levels
