Introduction

USB3319C-CP-TR is a three-level MOSFET gate driver circuit with embedded protector that is ideal for a variety of applications, such as automotive, consumer, and industrial. It is often seen in motherboards and shows outstanding performance in driving P-channel MOSFETs in harsh automotive environments. It has a wide temperature range, from -40°C to +125°C. This article will explore the working principle and application fields of this device.

Working Principle

The USB3319C-CP-TR typically works with three levels of MOSFET gate drivers, including ground, high-side and low-side. Ground is the source region of the MOSFET, the high-side is the drain region of the top MOSFET, and the low-side is the drain region of the bottom MOSFET. To facilitate the control of the entire MOSFET system, any of the levels can be made to be either high or low by setting the voltage/current levels of the corresponding gates. Through this intermediate step, the overall MOSFET system can be made to switch on or off. The USB3319C-CP-TR also contains an embedded protector, which provides enhanced inrush current protection and device protection from dust, impurities, and EMI. When using the device, the two MOSFETs must be connected so that one MOSFET is controlled by one of the two levels of logic and the other MOSFET is controlled by the other level of logic, in order to minimize the power distribution and ensure the maximum efficiency.

Application Fields

The USB3319C-CP-TR is a high-performance device suitable for a variety of applications. In automotive applications, it is useful for driving P-channel MOSFETs. The device is also useful for controlling power distribution in battery management systems, fuel injection systems, and other automotive systems that rely on MOSFETs.In consumer and industrial applications, the USB3319C-CP-TR is useful for numerous tasks. It can be used to drive MOSFETs in motor controllers and power supplies. It can also be used to control P-channel and N-channel MOSFETs in DC-DC converters and power management ICs. In addition, it is ideal for controlling the gate of switching power MOSFETs for low power or high power applications. In addition, the embedded protector makes the USB3319C-CP-TR an ideal choice for applications where EMI/RFI protection and surge current protection are required.

Conclusion

The USB3319C-CP-TR is a three-level MOSFET gate driver with embedded protector. The device is suitable for a variety of applications, ranging from automotive to consumer and industrial. It can be used to drive P-channel MOSFETs in automotive systems, as well as MOSFETs in motor controllers, DC-DC converters, power management ICs, and other similar devices. The embedded protector makes the device ideal for applications where EMI/RFI protection and surge current protection are required.
