MAX14515 Datasheet | Maxim Integrated

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 pact lens driver solution with minimal external 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 I2C interface to set the amplitude. The high-voltage outputs are capable of delivering up to 42VRMS (min) into a 220p F liquid lens load at 1.0k Hz (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 I2C interface to reduce current below 500n A (max). In sleep mode, the power-on reset circuit remains active. If no activity is detected on the I2C interface, current consumption is less than 3µA. The MAX14515 operates over the +2.7V to +5.5V supply 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.
