PMIC (Power Management ICs) offer power control design engineers a wide range of control, monitoring and power management solutions. Among all the PMICs, Gate Drivers are used to switch large currents in high-power systems, so they are extremely important to power electronics. The UCC27200DRMT is a cost-effective gate driver optimized for synchronous MOSFET or IGBT switching applications.

Application Field of UCC27200DRMT
The UCC27200DRMT was designed for low-side and high-side drivers for motor control, field-oriented control (FOC) applications. It can drive gated power switches such as MOSFETs and IGBTs with a wide variety of gate drive currents up to 8 A peak pulse current. The UCC27200DRMT accepts input logic which is compatible with low-voltage ICs and supplies logic level output gate drive for MOSFET or IGBT devices.The internal gate-drive UVLO (Under Voltage Lock Out) feature provides a convenient way to protect system power switches against loss of gate drive in case of an under voltage condition. Other features are integrated isolated supply, Over Temperature Alert output and open collector drive signal with high voltage output impedance.

Working Principle of UCC27200DRMT
The basic principle of the UCC27200DRMT is to serve as an interface between the logic device and the power switch. When a logic signal is applied to the input, the outputs of the UCC27200DMRT will switch, providing the required gate drive for the power switch. The input and output signals must be compatible with the voltage levels of the circuitry. The output gate drive feature of the UCC27200DRMT is capable of driving both high side and low side MOSFETs or IGBTs.

In addition to its switching capabilities, the UCC27200DRMT provides protection against a wide range of faults that can occur in high power applications. The UVLO feature ensures that the gate drive is turned off whenever the input voltage is below its predetermined threshold, thereby limiting the switching losses to an acceptable level. The Over Temperature Alert output will also alert the user when the die temperature exceeds a pre-determined limit.

The UCC27200DRMT features a radiation- immune power supply. This isolates the UCC27200DRMT from any interference from other circuits, preventing noise from affecting its operation. The device also features a unique open collector drive signal that outputs a high voltage output impedance, reducing the losses due to the off-state gate drive of the power switches.

The UCC27200DRMT has a wide operating temperature range, from -40°C to +85°C, making it suitable for a range of applications. This device also has over-voltage protection, over-current protection, and short-circuit protection, providing a robust and reliable interface between the power switches and the logic device.

In summary, the UCC27200DRMT is a cost-effective gate driver which is optimized for synchronous MOSFET or IGBT switching applications. Its integrated isolated power supply, Over Temperature Alert output, and high voltage output impedance make it a great choice for low-side and high-side drivers in motor control, field-oriented control (FOC) applications. Its wide operating temperature range, extensive protection features and radiation-immune power supply make it an ideal choice for power management ICs.
