Overview

SGM3132 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 specifi...
