General Description

        ET93011 is a inductorless LED flash driver that provides a high level of adjust-ability within a ultra-small size. It can produce up to 1.5A of LED flash current. The 128 levels current source provides the flexibility to adjust the current ratios in Flash/Torch/IR modes. An adaptive regulation method ensures the current source remain in regulation and maximizes efficiency. It also provides IVFM protection mode to prevent system reset or shutdown under low battery condition.

        ET93011 are controlled via an I2C compatible interface. These features include: flash/torch current, flash timeout duration, IVFM, under-voltage Protection. The device offers programmable currents in a Flash or Movie Mode (Torch) condition, and also provides hardware flash pin (STROBE) to control Flash events.

        ET93011 is available in WLCSP8 package and operates ambient temperature range of -40℃ to +85℃.
