The UCC27322D is a high-speed, high-current single-channel gate driver designed by Texas Instruments for driving MOSFETs and IGBTs. This driver is capable of delivering peak currents of up to 4A with extremely short propagation delays, making it an ideal choice for high-frequency and high-efficiency switching applications.
Key Features
- Peak Output Current: Capable of driving peak currents of 4A, ensuring efficient charging and discharging of gate capacitance.
- Input/Output Delay Time: Fast propagation delays of approximately 25ns provide precise control over switching times, which is critical for high-frequency operations.
- Dual Outputs: Offers both inverting and non-inverting outputs to provide flexibility in control schemes and to simplify the design of push-pull configurations.
- Bootstrap Operation: Suitable for high-side gate drive applications with bootstrap circuitry, enabling the driving of N-channel MOSFETs and IGBTs in half-bridge configurations.
- Supply Voltage Range: Operates over a wide supply voltage range from 4.5V to 15V, compatible with various logic levels and providing versatility across different power systems.
- Robust Design: Features under-voltage lockout protection, which ensures reliable operation by turning off the output when the supply voltage is insufficient.
