The HV892 liquid lens driver 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 single byte (AMP) written to the HV892 controls the operation of the driver. Setting AMP = 01h to FFh controls output amplitude in 255 monotonic steps. Setting AMP = 00h causes the HV892 to go into low power standby mode, consuming less than 1.0µA. When active, the HV892 draws less than 20mA. A charge pump boost converter integrated on-chip provides the high voltage necessary for driving the lens. No external inductors or diodes are needed. Two ceramic chip capacitors are the only external components required for a complete 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. The HV892 is offered in a 10-Lead 4x4mm DFN package.
