封装管脚图产品描述The SGM3139 is a 6-channel ultra low dropout constant source parallel LED driver. The SGM3139 uses an internal resistor to set the bias current for six LEDs, which are matched to ±3%. The SGM3139 incorporates a single wire interface to program the output current at 16 continuous steps. It has an internal deglitch circuit for filtering the noise of the EN input. The SGM3139 requires only a 35mV dropout voltage at a 20mA load. The feature makes SGM3139 ideal for battery-operated systems, such as personal digital assistants. The SGM3139 is available in Green TQFN-3 × 3-16L and TDFN-3 × 3-10L packages and is specified over an ambient temperature range of -40°C to + 85°C .产品特性Ultra Low Dropout: 35mV/20mASupport up to 6 LEDsLED Sink Current 20mA±3% LED Current MatchingDeglitch CircuitThermal Shutdown Protection16-Step Brightness ControlNo EMI and Switch NoiseOperating Temperature Range: -40°C to +85°CAvailable in Green TQFN-3×3-16L and TDFN-3×3-10L Packages
