Description

The E910.35 IC is developed for automotive applications. It continuously monitors the status of two groups of switch contacts connected to GND or VBAT.

The E910.35 input currents are compared to internal references. The IC is designed to operate with an external resistor of 1kΩ.

If the E910.35 switch resistance is less than 1.5kΩ the IC will lead into an active state (1 for switches to VBAT and 0 for switches to GND). If the resistance will be more than 9kΩ than the IC will switch to the corresponding inactive state. 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.
