HV892  
Inductorless Liquid Lens Driver  
General Description  
Features  
The HV892 liquid lens driver is controlled via an I2C interface, is  
capable of driving capacitive loads of up to 200pF, and is compatible  
Drives capacitive loads up to 200pF  
Programmable drive amplitude (compatible with  
40VRMS to 60VRMS lenses)  
with 40VRMS to 60VRMS lenses.  
On-chip boost converter  
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.  
No external inductor  
I2C interface  
Low operating current (≤20mA)  
Low standby current (≤1.0µA)  
Controlled drive edge reduces EMI  
10-Lead 4x4mm DFN Package  
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.  
Applications  
Cell phone cameras  
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.  
PDA and ultracompact cameras  
Bar code readers  
Web and laptop cameras  
The HV892 is offered in a 10-Lead 4x4mm DFN package.
