SGM37863A Inductorless LED Flash Driver with 1.5A High-Side Current Source

PublishTime：2024-09-05

●GENERAL 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℃. ●FEATURES ■Optional Working Mode and Programmable LED Currents ▲Flash/IR Mode: 16mA to 1.5A with 128 Levels ▲Torch Mode: ◆4mA to 388mA with 128 Levels when I_TORCH_SEL = 0 ◆3mA to 204mA with 128 Levels when I_TORCH_SEL = 1 ■2.7V to 5.5V Input Voltage Range ■Flash Timeout Ranges: 40ms to 1600ms ■I²C Port for Flexible Working Mode Setting and Status Reporting ■Hardware Flash Enable (STROBE) ■Optimized Flash LED Current with Input Voltage Flash Monitor (IVFM) ■LED Short Fault Protection ■Thermal Scale-Back and Thermal Shutdown ■Available in a Green WLCSP-0.8×1.5-8B Package
