PMIC – Gate Drivers are evolving quickly with advances in semiconductor technology, as well as increasing demand for higher power, higher switching frequency and lower on-resistance. The MC33395TEWR2 gate driver IC is at the forefront of this technology and combines a series of functions that make it a powerful solution for today’s power management applications. In this article, we will explore the MC33395TEWR2 application field and working principle.First of all, the MC33395TEWR2 is designed as a cost-effective solution for high-current, high-voltage power switch applications. It is suitable for powering permanent magnet synchronous and brushless DC (BLDC) motors, as well as voltage regulators, LED drivers and other power conversion applications. The MC33395TEWR2 is available in two sizes, the 8-pin SOIC and 16-pin QFN packages.The main features of the MC33395TEWR2 include a 3.2 A sink and source rating, up to 600V isolation, 6V to 24V operating voltage, up to 600ns switching time, and an adjustable 0.5V to 4.5V turn on voltage. Additionally, the device features low quiescent current of 2 mA, along with adjustable current control, dead time, and fault protection.The MC33395TEWR2 IC works by supplying a low-voltage control signal to activate two internal high-side and low-side MOSFETs, which then control the switching of current. This makes it suitable for driving both Power MOSFETs and IGBTs in power conversion applications, as well as controlling the speed of motors.Furthermore, the MC33395TEWR2 incorporates fault protection features, such as short-circuit protection, over-temperature protection, and short-circuit detection. These features ensure that the MOSFETs are not damaged, allowing the system to remain reliable and operational. The protection features are also adjustable via external components or via the device’s embedded trim resistors.In addition, the device also features an adjustable dead time control and adjustable current control. The dead time control feature allows the user to adjust the time between the high-side and low-side MOSFETs, ensuring that the devices remain turned off for a set amount of time. The dead time control also prevents shoot-through situations from occurring.The current control feature on the device also allows the user to adjust the amount of current that is flowing through the MOSFETs. The current can be adjusted from 0.25 A to 3.0 A, which makes the device suitable for applications with large currents.Lastly, the MC33395TEWR2 is designed for operation in harsh environments, featuring a wide operating temperature range from -55 ˚C to +125 ˚C. It also features an integrated overcurrent protection circuit, ESD protection, and voltage protection, which ensures that the device remains operational in demanding applications.In conclusion, the MC33395TEWR2 is a powerful and versatile solution for high-current, high-voltage power switch applications. Its features and low cost make it a great choice for applications such as motor control, voltage regulation, LED control and more. Moreover, its robust protection features, adjustable parameters, wide operating temperature range and easy operation make it an ideal choice for a variety of applications.
