AS1181 is an 8-channel highly integrated self-contained LED/VCSEL driver for near to eye applications such as Augmented Reality (AR) and Virtual Reality (VR) glasses. This eye-safety LED driver integrates extended safety monitoring functions to ensure eye-safe operation for smart glasses and other AR/VR applications. These safety monitors include LED short detection, LED open detection, LED overcurrent protection, LED on time monitor as well as temperature shutdown and a built-in-self test (BIST). The device is configurable via a serial wire interface (I²C or I3C) with interrupt and provides two Strobe/PWM inputs to synchronize illumination with up to two external cameras for binocular eye tracking systems. The LED current is individually programmable per channel, and it can drive up to 2 IR LEDs per current sink with a minimum ON time of 10μs and a maximum current of 66mA per channel. General purpose LED driving applications can be supported via a direct PWM input applied at the Strobe pin and it can drive RGB or white LEDs considering a maximum forward voltage of 5V. The device comes in a tiny wafer-level-chip-scale package (WLCSP) with 0.4mm pitch and dimensions of 2.9mm x 1 .75mm x 0.5mm (L x W x H).

The TMD2636 is an advanced IR proximity sensor module suited for short range proximity measurement detection and offered in the industry's smallest size (1.0mm x 2.0mm) and thin (0.35mm) optical land grid array module that incorporates a 940nm IR VCSEL and is factory calibrated for IR proximity response. The proximity detection feature provides nearby object detection by photodiode detection of reflected IR energy sourced by the integrated VCSEL emitter. Sensitivity, power consumption, and noise can be optimized with adjustable timing and power. Detect/release events can be interrupt driven, and occur when proximity result crosses upper and/or lower threshold settings. The proximity engine features advanced crosstalk noise cancellation through a wide range offset adjustments to compensate for unwanted IR energy reflection at the sensor. Proximity results are further improved by automatic ambient light subtraction.
