Description
General part information
HV892 Series
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.
