Electrostatic Actuator IC for Pico-Projector, 3D-scanning and HUD Systems

Teledyne DALSA’s Semiconductor Foundry, a division of Teledyne Technologies, announced today the availability of its DH0357AQ Electrostatic Actuator High-Voltage IC. Using proprietary High-Voltage CMOS/DMOS technology, the DH0357AQ’s high-accuracy, small footprint and low power is designed for portable miniature projection display engines in mobile and automotive applications. This device showcases Teledyne DALSA Semiconductor’s suite of product development and manufacturing capabilities for MEMS/CCD/HV-CMOS solutions.

"Low power, low noise high voltage design coupled with an efficient DC/DC boost converter and MEMS movement sensing permits us to electrostatically actuate one biaxial or two uni-axial MEMS Micro-Mirrors up to 280V" said Remi Meingan, Senior Product Manager. “With an I2C Interface and advanced QFN Package, the DH0357AQ is the ideal solution to generate the optical raster patterns for the repetitive horizontal sweeping and precise vertical scanning motions in pico-projector, head-up display and optical MEMS applications."

The DH0357AQ is a cost-effective solution for mobile platforms, is RoHS compliant, requires an external miniaturized surface mount coil and is packaged in TQFN 44L, 6x6mm, 0.4P. The DH0357AQ will be available in April. Key features include: 280V, two HV analog channels and one HV digital channel fully-programmable through I2C Interface; 100V to 280V high-voltage supply generated from a dc-dc boost converter with internal power MOSFET; and op amps for fast and slow MEMS movement sensing.
