Industry's Smallest Liquid Lens Driver for Tiny Autofocus Camera Modules - New Product Release

Industry's Smallest Liquid Lens Driver for Tiny Autofocus Camera

Modules

SUNNYVALE, CA—December 4, 2008—Maxim Integrated Products (NASDAQ:

MXIM) introduces the MAX14515, a DC-to-AC liquid lens driver for autofocus

(AF) camera modules. The MAX14515 features a high-voltage differential output

controlled through an I²C interface. It employs a charge-pump topology to

reduce the number of external components typically used for autofocus drivers in

camera modules. The I²C interface and the charge-pump topology are combined

in a tiny 2mm x 1mm WLP, making the MAX14515 the industry's smallest liquid

lens driver. The device is ideal for tiny cell-phone camera modules that use the

newest autofocus technologies.

Traditional Solutions Too Large for Shrinking Camera Modules

The traditional liquid lens drivers available on the market require components

typically found in boost topologies, which minimally include a large inductor, diode, and high-voltage capacitor. Meanwhile, other

charge-pump-based drivers are large and require many capacitors. When the numerous other supporting discrete components

are added to the design, the size of these discrete solutions requires a large footprint, one that can no longer be accommodated

inside the shrinking autofocus camera modules.

High Integration and High Performance for Tiny Camera Modules

The MAX14515 needs at most two small external capacitors: one low-voltage capacitor and a tiny bypass capacitor. The device

integrates an 8-bit monotonic DAC with a single-differential high-voltage output controlled by a 2-wire I²C interface to set the

amplitude. The high-voltage output delivers up to 42V

is at least 60% smaller than the market's available drivers, the MAX14515 liquid lens driver easily fits inside the camera module.

The unique combination of smallest footprint, I²C interface, and low shutdown current make the MAX14515 ideal for enabling

today's newest high-performance, autofocus camera modules.

The MAX14515 is fully specified over the -40°C to +85°C extended temperature range. The device is priced at $1.50 (1000-up,

FOB USA). For more information please visit: www.maxim-ic.com/MAX14515-Driver.
