                4-Channel 1-Wire Dimming LED Driver with Ultra-Low Dropout Current Source
                GENERAL DESCRIPTION

                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 TQFN-3×3-16L, TDFN-2×2-8L and MSOP-8 packages and is specified over an ambient temperature range of -40 to +85.
