Global shutter sensors target automotive DMS/OMS

Omnivision has expanded its Nyxel near-infrared (NIR) technology family with the launch of two new global shutter sensors for automotive in-cabin applications. The OX02C1S is a 2.5‑megapixel (MP) RGB‑IR BSI global shutter sensor for in-cabin driver and occupant monitoring systems (DMS and OMS) and the OX01H1B is a 1.5-MP mono (IR) global shutter sensor for driver monitoring systems (DMS).

Both new sensors, with a pixel size of 2.2 microns (µm), claim industry-leading NIR quantum efficiency (QE) at 36%, a significant increase in modulation transfer function (MTF) over the previous 3.0-µm FSI GS pixel design and “extremely” low power consumption.

The OX02C1S, in a 1/3.52‑inch optical format, and the OX01H1B, in a 1/4.51‑inch optical format, both use Omnivision’s OmniPixel4‑GS technology. This “enables simultaneous image detection in all pixels to accurately reproduce rapid motion without any deformation,” said Omnivision.

Both sensors integrate cybersecurity and safety features, which support ASIL-B. They also include an embedded temperature sensor and supply voltage monitor.

The sensors are available in a stacked a‑CSP package, allowing for higher-performance image sensors in tighter camera spaces, and in a reconstructed wafer option for customization. Samples are available now, followed by mass production in 2024.

The OX02C1S and OX01H1B join the 5-MP OX05B1S global shutter sensor introduced last year. With the same features and pixel technology, Omnivision said automotive OEMs can incorporate a combination of them in their line-up from high-end to mainstream vehicles.
