Microchip Technology HV892 Liquid Lens Driver Demoboard

Microchip Technology HV892 Liquid Lens Driver Demoboard is controlled via an I²C interface capable of driving capacitive loads of up to 200pF. This lens driver demo board is compatible with 40V_RMS to 60V_RMS lenses. The charge pump boost converter integrated on-chip provides the high voltage necessary for driving the lens. The HV892 lens driver demo board requires only two ceramic chip capacitors to complete a lens driver circuit. The 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.
