UCC27525DR Typical application Circuitry

UCC27525DR

Power MOSFETs and IGBTs in a variety of switching applications are driven by the UCC27525DR, a dual-channel, high-speed gate driver. Power-switching circuits, motor drives, and power converters are among its many uses.

Principal characteristics:

- Large power devices can be powered by the high peak output current of up to 5A.

- A broad variety of supply voltages, from 4.5V to 18V, to support different power systems.

- Fast propagation delay and rise/fall times, enabling high-frequency operation.

Circuit Design for a Half-Bridge Configuration:

1. Input Connections: Connect the input signals to the input pins (IN1 to pin 2 and IN2 to pin 6) for controlling the high and low side drivers.

2. Output Connections: Attach the outputs (OUT1 to pin 1 and OUT2 to pin 7) to the gates of the high and low side MOSFETs in the half-bridge.

3. Bootstrap Circuit: Implement a bootstrap circuit with a diode and capacitor connected between VDD (pin 8), HB (pin 3), and the SW node to provide a floating supply for the high-side driver.

4. Power Supply: Apply a supply voltage within the specified range to VDD (pin 8) and connect GND (pin 4) to the system ground.

5. Enable Function: Utilize the enable pin (EN, pin 5) to enable or disable the driver outputs. Tie it high for normal operation or low to disable the outputs.

Considerations for Circuit Design:

- Dead Time Control: To avoid shoot-through, make sure there is enough dead time between the high and low side drivers.

- Decoupling Capacitors: To stabilize the supply voltage, place decoupling capacitors in close proximity to the VDD and GND pins.

- Thermal Management: Consider heat dissipation for the UCC27525DR, especially in high-frequency applications.

In this half-bridge application, the UCC27525DR efficiently drives the high and low side MOSFETs, enabling precise control of power switching. The UCC27525DR circuit design considerations emphasize the importance of dead time control, supply voltage stability, and thermal management when using the UCC27525DR in power conversion and motor drive applications.
