DESCRIPTION
The IC is designed for use in electric power window systems to store and display the status of a childproof lock function of the rear windows. The actual status is stored in three bits of the EEPROM whenever switch activity is detected. The redundant information is checked periodically by a two out of three selection and in case of one bit distinguishes from the others, the dominant information is stored in all three EEPROM cells again.

FEATURES
► Supply voltage range VS 6.9V to 19V
► On chip voltage clamping
► Under voltage reset
► Charge pump to generate programming voltage
► Redundant non - volatile memory
► Periodical check of data consistency
► Automatic data correction in case of inconsistency
► Two I/Os to detect switch activation and drive LEDs
► – 40°C to + 85°C operating temperature
► SO8n package

APPLICATION
► Status IC for switches
