Working Principle

The SSL2109T/1,118 is a high speed power MOSFET driver IC. Its purpose is to provide good thermal performance and low on resistance in a lower profile thermally enhanced package. It can handle a wide variety of switching operations, such as dimming and drives, with high accuracy over a wide range of frequencies. The SSL2109T/1,118 uses an “on” and “off” control to operate the LEDs. It operates from a logic voltage range of 0V - 5.5V, which enables logic level driven control.

In addition to providing thermal performance, the SSL2109T/1,118 also offers surge protection. This feature helps protect LED’s from sudden spikes in voltage and current that would ordinarily cause damage.

The SSL2109T/1,118 is designed to operate as a linear regulator of current. It works by driving the MOSFET gate in an “on” and “off” fashion, thus regulating the output current or the LED’s brightness. The device also has short-circuit protection, allowing the device to sense when there is a short circuit between the PWM input and the drain connection, thus protecting the LEDs from short-circuits.

Conclusion

The SSL2109T/1,118 PMIC-LED driver is a high speed power MOSFET driver IC that is built to operate under many different conditions while not compromising on performance. This device provides great thermal performance and low on resistance in a low-profile, thermally enhanced package. It can be used in many applications, including LED backlights, LCDs, car headlights and more, and is suitable for use in harsh and extreme environments. The device operates from a logic voltage range of 0V - 5.5V, which makes it convenient and easy to use.
