PMIC - Gate Drivers are electronic components that regulate the current flow in a particular circuit. The UCC37325DR is one such gate driver and it is designed for use in SMPS (Switch Mode Power Supply) systems.

The UCC37325DR is a high performance dual channel gate driver IC designed to improve efficiency and reduce the size of power supply systems. It offers two channels for driving both high and low side MOSFETs and IGBTs. It supports up to 20V and is capable of providing up to 2A peak current. It also incorporates active clamping protection, which greatly reduces the propagation delays associated with switching high side power MOSFETs.

The UCC37325DR is a multipurpose IC that can be used in a wide range of applications. It can be used in battery chargers, motor control, lighting control, and in the switch mode power supply systems. It can also be used in automotive applications where it can be used to control electric vehicles, mild Hybrid Electric Vehicles (HEVs), and diesel motorstarter systems.

The UCC37325DR has two main operations: one operating as a high side MOSFET driver, and the other as a low side MOSFET driver. The high side MOSFET driver is used to supply a large current to the high side of the power circuit, while the low side MOSFET driver supplies a smaller current to the low side of the power circuit.

In the high side MOSFET driver, the UCC37325DR uses a high side N-Channel MOSFET that is driven in parallel with the gate voltage of the switch. This is beneficial as it allows for fast switching speeds and improved performance. In addition, the UCC37325DR is designed to minimize power losses due to its switching capability, improving efficiency.

The low side MOSFET driver is used to power the low side of the power circuit. It uses two P-Channel MOSFETs in parallel with a logic controlled gate voltage of the switch. The UCC37325DR is designed to reduce power losses and improve efficiency by detecting the current drawn by the low side MOSFETs and adjusting the gate voltage accordingly.

The UCC37325DR is a versatile and reliable gate driver IC, and is suitable for use in a wide range of applications. It is also highly configurable, allowing users to customize the functionality of the driver to fit the requirements of their specific application. It is designed to reduce power losses and maximize efficiency, making it an ideal choice for power supply systems.
