- SGM31324
The SGM31324 is a 3-channel, current-regulated RGB LED driver with an I2C-compatible interface. It is well suited for various applications powered by a 1-cell Li-Ion or Li-Polymer, or systems with 3.3V or 5V supply voltages, as well as 3-cell NiCd, NiMH or Alkaline batteries. No external components are required for the three constant current sinks.
With two programmable timers, users can adjust LED blinking time and get the result of fade-in and fade-out for unique color lighting.
Programmable I2C interface allows independent channel control for LED ON or OFF state and LED brightness due to 10 internal registers and an internal decoder. Each current sink can be independently configured with 192-step current levels from 0.125mA to 24mA. The SGM31324 provides less than 1μA shutdown current.
An automatic blink mode allows the LED on D1 pin (LED1) ON/OFF automatically at an 8mA load every 2 seconds after the EN pin is pulled high.
The SGM31324 is available in a Green UTDFN- 1.5×1.5-8L package. It operates over an ambient temperature range of -40℃ to +85℃.
