The Texas Instruments LP3943ISQ is an integrated circuit designed to independently drive 16 LEDs, making it suitable for applications such as camera flash. This device operates with an input voltage range of 2.3V to 5.5V and can deliver up to 25mA per channel.
Control is managed via I2C or SMBus interfaces, allowing for versatile dimming capabilities with variable dim rates from 6.25ms to 1.6s. The LP3943ISQ features an internal precision oscillator for timing and provides 16 open-drain outputs. It is packaged in a 24-WQFN (4x4mm) surface-mount configuration.
Key electrical characteristics include a typical quiescent current of 0.35mA and a shutdown current of 2µA. The operating temperature range is -40°C to 85°C. The device utilizes a shift register topology and includes internal power-on reset functionality.
