ON Semiconductor offers automotive-grade version of CMOS image sensor

An AEC-Q100-qualified version of ON Semiconductor’s 2.1Mpixel CMOS image sensor, the AR0237, has been released. It is aimed at the OEM-fitted dashboard cameras (dash cams) or before-market in-car DVR market.

Demand for safety cameras is rising, as more insurance companies offer financial incentives, prompting car manufacturers to offer dash cams as standard equipment. The AR0237AT is a cost-optimised, automotive-qualified version of the same sensor selected by many manufacturers producing after-market dash cams, which offers full HD video capture at 1080p/60 frames per second, as well as still image capture. As the application moves into the before-market category, there is mounting demand from the automotive industry for an image sensor that can operate across the full automotive operating temperature range of -40 to +105 degree C for the cost-sensitive automotive market. The low-light performance of the AR0237AT is further improved when it is coupled to a Clarity+ enabled DVR processor, claims ON Semiconductor. Its Clarity+ technology uses filtering to optimise the signal to noise ration (SNR) of automotive imaging, which can deliver an additional two-fold increase in light capture.

“The AR0237AT delivers the same outstanding performance as the non-automotive qualified part, providing impressive daytime color and night time near-infra red image capture from the same sensor,” said Ross Jatou, vice president and general manager, automotive solutions division of Image Sensor Group at ON Semiconductor. “We achieve this without the need for an IR-cut filter, while the high dynamic range means the sensor continues to perform even under changing light conditions.” He adds that by moving the image processing off chip and qualifying the device to AEC-Q100, ON Semiconductor provides design flexibility and performance for automotive manufacturers, at a competitive price.

The AR0237AT is available now in an IBGA-80 package, measuring 10 x 10mm.

ON Semiconductor offers a portfolio of energy-efficient, power management, analogue, sensors, logic, timing, connectivity, discrete, SoC and custom devices.
