SemtechNew driver for better mobile photography : poLight, the world leader in high-speed and ultra-low power autofocus actuated lenses, together with Semtech Corporation, announced the availability of the first driver for better mobile photography, dedicated to the TLens platform. This ultra-small 8-pins driver for better mobile photography will perfectly integrate into small camera module designs to drive the TLens to its best performance. poLight has developed three different actuated autofocus devices based on a patented technology using its optical MEMS and polymer. This technology is to be integrated in camera modules based on 1/5” to 1/2.5” sensor format, reaching 5MP to 12MP and higher resolutions for better mobile photography.

Mobile photography enhanced by new driver
Semtech announced the availability of its SX8750 driver for capacitive and piezoelectric actuators targeting next generation Mobile Phone and PC camera modules. The Semtech SX8750 mobile photography driver, optimized for the poLight TLens’s new technology, enables faster auto-focus, enhanced image quality and a smaller form factor camera module. The Semtech SX 8750 platform combines high voltage and ultra-fast driver technology with ultra-low current consumption from 3V with no external coil. These unique features combine to drive MEMS based actuators for a larger camera resolution and a true real-time auto-focus, now up to 20x faster than traditional VCM technology, at a fraction of the power consumption.
