General Description

The MAX14515 high-voltage liquid lens driver features a high-voltage differential output controlled through an I2C interface. The MAX14515 uses a charge-pump-based boost converter and integrated H-bridge to provide a compact lens driver solution with minimal external components to achieve a small overall footprint suitable for small space constraints inside camera modules.
