SGM3795数据手册SGMICRO中文资料规格书

描述 Description

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.
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.
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.
