封装管脚图产品描述The SGM3132 is a 4-channel ultra low dropout constant source parallel LED driver. The SGM3132 uses an internal resistor to set the bias current for four LEDs. The SGM3132 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 SGM3132 requires only a 35mV dropout voltage at a 20mA load. The feature makes SGM3132 ideal for battery-operated systems, such as personal digital assistants. The SGM3132 is available in Green TQFN3×3-16L, DFN2×2-8L and MSOP8 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 4 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 , TDFN-2 × 2-8L and MSOP-8 Packages
