Product Overview
The LM36011 is a Texas Instruments single LED flash driver categorized under Power_Management. It is intended for controlled flash, IR, and torch/movie LED current delivery, with a recommended input voltage range of 2.5 to 5.5 V. Flash/IR current is programmable from 11 mA to 1.5 A in 128 levels, while torch/movie current is programmable from 2.4 mA to 376 mA in 128 levels.
The device uses an I2C-compatible control interface operating at 400 kHz with address 0x64. A STROBE pin provides active-high hardware flash enable, and the flash timeout is programmable up to 1.6 s. Logic thresholds are specified for STROBE and I2C pins, including 0 to 0.4 V low and 1.2 V to VIN high ranges under stated VIN conditions.
Assembly is based on the YKB 8-pin DSBGA package, with a 1.512 mm x 0.800 mm nominal body. Pin functions include IN, GND, STROBE, SDA, SCL, LED output, and one no-connect pin. The IN supply should be bypassed to GND with a 10 µF or larger ceramic capacitor.
