UCC27517AQDBVRQ1 single-channel gate driver
The UCC27517AQDBVRQ1 from Texas Instruments is an automotive-grade, single-channel gate driver designed to efficiently control MOSFETs and IGBTs in high-speed switching applications. This device features a split-output configuration, allowing independent optimization of turn-on and turn-off strength by using separate sink and source pins. With a wide operating voltage range of 4.5 V to 18 V, it delivers peak source/sink currents of 4 A and 8 A, respectively, ensuring rapid switching of power transistors while minimizing losses. Housed in a compact SOT-23-6 package, the driver incorporates 5 V TTL/CMOS compatible input logic with hysteresis for robust noise immunity, making it ideal for automotive systems like DC-DC converters, motor drives, and onboard chargers where reliability and efficiency are critical. Its AEC-Q100 Grade 1 qualification ensures performance across -40°C to +125°C ambient temperatures.
UCC27517AQDBVRQ1 Key Features
This gate driver excels in switching performance with typical rise/fall times of 7 ns and 6 ns (at 1,800 pF load), enabling frequencies up to several MHz. The asymmetric sink/source current capability (8 A sink vs. 4 A source) accelerates Miller plateau transitions, reducing shoot-through risks in half-bridge topologies. Key specifications include a fast propagation delay of 13 ns (typical), minimal pulse-width distortion, and tight channel-to-channel matching. The device features an enable pin (EN) for proactive system control, undervoltage lockout (UVLO) protection to prevent faulty operation at low VDD, and a wide input voltage range compatible with 3.3 V/5 V microcontrollers. With a quiescent current of 1.7 mA and standby current below 1 μA when disabled, it balances high performance with low power consumption.
