MAX14515 high pressure liquid lens driver

MAX14515 high pressure liquid lens driver The MAX14515 high-pressure liquid lens driver provides high pressure differential output through the I2C interface. The MAX14515 uses charge pump-based boost converters and integrated H-bridge techniques, with minimal external components to achieve microscopic drivers, small-sized packages can be used for space-limited camera modules. The MAX14515 integrates 8-bit monotonic DAC, and the differential high voltage output is controlled by the 2-wire I2C interface for setting the output amplitude. The high voltage output provides a voltage driver of up to 42VRMS (minimum) at a liquid lens of 200 pF at 1.0 kHz (minimum) frequency. The MAX14515 also has two power saving modes (shutdown mode and sleep mode) that minimizes the device when the device stops. The device is placed in a low power state in the shutdown mode. At this point, all registers are reset and the I2C interface is prohibited, so that the power supply is reduced to 500na (max). In sleep mode, power-on reset circuit remains valid. If there is no operation detected by I2C interface, the current loss is less than 3μA. The MAX14515 works in a + 2.7V to + 5.5V supply voltage range, and ideal for portable devices for lithium batteries. The MAX14515 works in -40 ° C to + 85 ° C expanded temperature range, using small (1 mm x 2mm) 8 solder ball WLP package. Tin size is very suitable for placing inside the camera module 47VRMS maximum output voltage (CLENS = 220pf) I2C compatible interface is used to set out output voltages 8-digit output voltage resolution Reliable monotonic output Output end has ± 15kV human mode ESD protection 500NA (max) low shutdown current + 2.7V to + 5.5V input voltage range Save space 8 solder ball WLP (1mm x 2mm) package, technology area Heilind won the title of "2017 Huaqiang Electronic Network Quality Supplier" Tas5634300W stereo PurePath (TM) HD digital input efficient power level TAS2557 5.7W D-class audio amplifier with H-class boost and speaker detection function Ruckus NetWorks appointed Deng Weidong for the general manager of China China Site Electronic Technology Forum - Power Technology Practice Seminar held in Wuhan
