Gate Drivers ICs

UCC27321DGN Description

The UCC27321DGN from Texas Instruments is a high-performance, single-channel low-side gate driver designed for power MOSFET and IGBT applications. Housed in an 8-MSOP package, this surface-mount IC operates over a 4V to 15V supply range, delivering 9A peak source/sink current for fast switching. With 20ns rise/fall times, it ensures minimal switching losses, making it ideal for high-frequency applications. The inverting input logic (VIL = 1V, VIH = 2V) simplifies interfacing with control circuits. Its ROHS3 compliance and REACH-unaffected status align with environmental standards, while the Last Time Buy status indicates end-of-life availability.

UCC27321DGN Features

• High Peak Current: 9A source/sink enables robust gate drive for high-power FETs/IGBTs.
• Fast Switching: 20ns rise/fall times reduce transition losses in high-frequency designs.
• Wide Voltage Range: 4V–15V operation supports diverse power architectures.
• Inverting Input: Simplifies logic-level interfacing with controllers.
• Robust Packaging: 8-MSOP offers compact footprint for space-constrained PCBs.
• Reliability: MSL 1 (Unlimited) moisture sensitivity ensures handling flexibility.

UCC27321DGN Applications

• Switch-Mode Power Supplies (SMPS): Enhances efficiency in buck/boost converters.
• Motor Drives: Drives IGBTs in industrial BLDC/PMSM controllers.
• Solar Inverters: Optimizes switching in PV power stages.
• Class-D Amplifiers: Ensures low-distortion switching for audio applications.
• LED Drivers: Provides precise gate control in high-current LED systems.

Conclusion of UCC27321DGN

The UCC27321DGN excels in high-speed, high-current gate-driving applications, offering a blend of speed, power, and compactness. Its inverting logic and wide voltage range make it versatile for power electronics, though designers should note its Last Time Buy status. Ideal for SMPS, motor drives, and inverters, this driver is a reliable choice for engineers prioritizing performance and efficiency in switching systems.
