SGM37863A数据手册SGMICRO中文资料规格书

描述 Description

The SGM37863A is a single LED flash driver that is compact and highly customizable. The constant current LED source allows for flexible adjustment from 16mA up to 1.5A in flash mode, and from 4mA up to 388mA or from 3mA up to 204mA in torch mode, each with 128 levels. The current source does not require pre-regulated voltage, and thus it saves the size and cost of the solution. 
The SGM37863A features include an I2C interface for management, hardware flash enable pin (STROBE), flash timeout and input voltage flash monitor (IVFM). The protection functions include UVLO, LED short protection, thermal scale-back (TSB) and thermal shutdown (TSD). The recommended operating temperature range is from -40℃ to +85℃.
