Inductorless, Liquid Lens Driver Demoboard (HV892DB1)

The HV892DB1 liquid lens driver demoboard is controlled via an I2C interface, is capable of driving capacitive loads of up to 200pF, and is compatible with 40VRMS to 60VRMS lenses. A charge pump boost converter integrated on-chip provides the high voltage necessary for driving the lens. No external inductors or diodes are needed. The board requires only two ceramic chip capacitors to complete a lens driver circuit. An H-bridge output stage provides AC drive to the lens, allowing the use of a single high voltage boost converter while providing alternating polarity to the lens. Controlled rising and falling edges on the drive waveform reduces EMI.

PLEASE CONTACT YOUR LOCAL MICROCHIP SALES OFFICE FOR DEMO BOARD AVAILABILITY.
