Overview

Safety Controller for Infra-Red LED Illumination to Complement the Image Sensor for Automotive Applications NCV7694 The NCV7694 is a device which can drive a string of infra−red LEDs using an external mosfet.

The IR LEDs are used to illuminate the surroundings of the image sensor.

Since these LEDs can damage the end users’ eyes, the power feed to the LEDs needs to be turned off during a fault condition.

Key Features

  • prevents the IR LEDs from being on too long due to an inappropriate exposure time or being turned on too frequently using external resistors. The value of the RETL resistor defines the maximum TON time of the emitted light intensity and the value of the RFRL resistor defines the maximum frequency of the FLASH signal from the image sensor. A LED driver with hardware interlocks helps protect the users’ eyes in cases where the control signal has failed or a fault in the LED power path has occurred.
