Teledyne DALSA’s Semiconductor Foundry, a division of Teledyne Technologies, announced today the availability of its DH0485A Electrostatic Actuator High Voltage IC. Using proprietary High Voltage CMOS/DMOS technology, the DH0485A’s high accuracy, small footprint and low power is designed for portable systems containing MEMS Micro-Mirrors with up to 4 electrodes.
This device showcases Teledyne DALSA Semiconductor's suite of product development and manufacturing capabilities for MEMS/CCD/HV-CMOS solutions as required by ROADM, WSS, OXC and Integrable Tunable Lasers.
DH0485A Electrostatic Actuator High Voltage IC
"Sophisticated High Voltage design permits us to electrostatically actuate one biaxial or two uni-axial MEMS Micro-Mirrors up to 240V" said Remi Meingan, Senior Product Manager. "With an internal DC to DC Boost Converter, a 16 Bit DAC with SPI Interface and advanced QFN Package, the DH0485A is the ideal solution for optical applications using MEMS Micro-Mirrors with 4 electrodes and needing accurate positioning.”
The DH0485A extends Teledyne DALSA's industry leading MEMS and MOEMS capability and provides a cost-effective solution for Optical MEMS. The DH0485A requires only a low voltage supply; the High Voltage Output is provided through a DC/DC Boost Converter up to 240V using an external miniaturized surface mount coil. The DH0485A is packaged in QFN 33L, 6x6mm, 0.5P and is ROHS compliant.
