general description the MAX14515 high-voltage liquid lens driver features a high-voltage differential output controlled through an i 2 c interface. the MAX14515 uses a charge-pump-based boost converter and integrated h-bridge to provide a compact lens driver solution with minimal external com- ponents to achieve a small overall footprint suitable for small space constraints inside camera modules. the MAX14515 features an 8-bit monotonic dac with a single differential high-voltage output controlled by a 2-wire i 2 c interface to set the amplitude. the high-volt- age outputs are capable of delivering up to 42v rms (min) into a 220pf liquid lens load at 1.0khz (min). the MAX14515 also features two power-saving modes (shutdown mode and sleep mode) to minimize power consumption when the device is inactive. shutdown mode places the device in a low-power state that resets all registers and disables the i 2 c interface to reduce cur- rent below 500na (max). in sleep mode, the power-on reset circuit remains active. if no activity is detected on the i 2 c interface, current consumption is less than 3?. the MAX14515 operates over the +2.7v to +5.5v sup- ply voltage range, ideal for portable applications using lithium ion battery sources. the MAX14515 is specified over the -40? to +85? extended temperature range and is available in a small (1mm x 2mm) 8-bump wlp package. applications autofocus camera modules barcode readers webcams features small footprint for placement inside camera modules 47v rms maximum output (c lens = 220pf) i 2 c-compatible interface for setting output voltage 8-bit output voltage resolution guaranteed monotonic output 15kv human body model esd protection on outputs low 500na (max) shutdown current +2.7v to +5.5v input voltage range space-saving, 8-bump wlp (1mm x 2mm) package MAX14515 high-voltage liquid lens driver ________________________________________________________________ maxim integrated products 1 top view (bump side down) wlp 1mm x 2mm pin configuration ordering information image signal processor gnd v b v a sda en scl 1.8v MAX14515 liquid lens v dd 2.8v 0.1f v ref 1f typical application circuit part temp range pin-package top mark MAX14515ewa+ -40? to +85? 8 wlp +aaa + denotes a lead-free/rohs-compliant package. for pricing, delivery, and ordering information, please contact maxim direct at 1-888-629-4642, or visit maxim's website at www.maxim-ic.com.
