SGM3795

700mA Quad Channel

Constant Current LED Driver

GENERAL DESCRIPTION

FEATURES

The SGM3795 is a general purpose high voltage quad

channel LED driver. 4 LED sink channels are well

matched with up to 175mA per channel and suitable for

high brightness LEDs or infrared LEDs. Each LED pin

is capable of supporting voltage up to 22V, which is

suitable for long strings of LED applications.

● Quad LED Sink Channels up to 175mA each

● Up to 22V LED Pin Operation Voltage

● 0.275V LED Dropout Voltage at 175mA Sink

Current

● Programmable LED Sink Current

● Programmable PWM Dimming Frequency

● Less than 1μA Shutdown Current

● LED Short Protection

The SGM3795 integrates device enable and external

PWM dimming control via the EN/PWM pin. Higher

dimming frequency, up to 50kHz with a minimal duty

cycle of 10% or higher, is allowed. The device also

implements LED sink current adjustment via the ISET

pin.

● Thermal Shutdown

● Available in a Green TDFN-2×3-8L Package

APPLICATIONS

Motion Tracking LED Sinks

General Lighting Applications

The SGM3795 implements various protection features

such as thermal shutdown and LED short protection.

The SGM3795 is available in a Green TDFN-2×3-8L

package. It operates over the -40℃ to +85℃ temperature

range.
