Modern electronics products are not complete without the help of Power Management Integrated Circuits (PMICs). PMICs serve important functions in the power management of electronics products, helping to regulate, monitor and control power operations for devices. One type of PMIC is a LED driver, which serves a special purpose in driving LEDs for optimal power performance.

SLG7NT4084V is a Quad NFET LED Driver from Silego. This PMIC is a high performance, low power, four-channel LED driver for driving LEDs with up to 8 W of power capacity. The SLG7NT4084V provides a wide input voltage range of 4.5 V to 28 V and features a programmable current sink of up to 250 mA per channel and power shutdown control.

Application Field

SLG7NT4084V is an ideal choice for applications that require high power efficiency, such as lighting and consumer electronics. The combination of wide input voltage range and programmable current sink allows this LED driver to accurately drive LEDs to their desired power levels. This makes it particularly suitable for LED lighting applications, where the driver can be used to adjust the brightness of the LED with accuracy and efficiency.

The SLG7NT4084V is also an ideal choice for automotive applications, thanks to its wide operating temperature range of -40°C to +125°C, allowing reliable operation in critical automotive environments. This LED driver also features I2C programmability, allowing for accurate control and monitoring of LED performance in automotive systems.

Working Principle

The working principle of the SLG7NT4084V is relatively simple. This LED driver consists of four discrete N-channel power FETs, each of which can be used to drive a single LED. When the input voltage is applied to the FETs, a current source is activated and the LEDs can be driven to the desired power level depending on the current source setting. The power shutdown control allows for the entire switch array to be shut down when not in use. This helps to reduce power consumption and extend the life of the LEDs.

The SLG7NT4084V also features I2C programmability, allowing for accurate control of the LED power levels. The I2C interface allows for direct control over the LED dimming levels, enabling the brightness of the LEDs to be set to any desired level. This makes it easy to adjust the LED power levels quickly and accurately, allowing for optimal LED performance.

Overall, the SLG7NT4084V is an excellent choice for LED lighting applications, due to its high performance, low power consumption and accurate power control. Its wide input voltage range, programmable current sink, I2C programmability and power shutdown control make it an ideal choice for driving LEDs in a variety of different applications.
