High-Voltage Liquid Lens Driver

MAX415

General Description

Features

o Small Footprint for Placement Inside Camera

Modules

The MAX14515 high-voltage liquid lens driver features a

high-voltage differential output controlled through an I 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.

= 220pF)

o 8-Bit Output Voltage Resolution

o Guaranteed Monotonic Output

The MAX14515 features an 8-bit monotonic DAC with a

single differential high-voltage output controlled by a

2-wire I C interface to set the amplitude. The high-volt-

age outputs are capable of delivering up to 42V

(min) into a 220pF liquid lens load at 1.0kHz (min).

RMS

o Low 500nA (max) Shutdown Current

o +2.7V to +5.5V Input Voltage Range

o Space-Saving, 8-Bump WLP (1mm x 2mm) Package

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 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 C interface, current consumption is less than 3µA.

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°C to +85°C extended temperature range

and is available in a small (1mm x 2mm) 8-bump WLP

package.
