Key Features
- Dual-channel gate driver with 5 A source and 5 A sink peak drive current per channel for fast switching of IGBTs and MOSFETs in automotive inverters
- 30 V rated outputs with reverse current protection prevent shoot-through and protect the driver from bootstrap or bootstrap diode failure transients
- Schmitt-trigger input thresholds provide hysteresis to reject noise on the PWM input lines in electrically noisy automotive environments
- AEC-Q100 automotive qualification and SOIC-8 package ensure reliable operation from −40°C to +125°C in traction, DCDC, and OBC applications
Applications
UCC27624QDRQ1 is used in automotive traction inverters, DC-DC converters, and on-board chargers (OBC) where dual-channel gate drivers with high peak current are needed to switch IGBTs or SiC/GaN MOSFETs at frequencies up to several hundred kHz. Its AEC-Q100 qualification and −40°C to +125°C operating range make it suitable for under-hood power electronics in electric vehicles and hybrid powertrains. Industrial motor drives and solar inverters also benefit from its 5 A peak drive strength and reverse current protection for reliable bootstrap-powered high-side gate drive.

Frequently Asked Questions
What peak gate drive current does UCC27624QDRQ1 provide per channel and why does it matter for fast switching?
UCC27624QDRQ1 delivers 5 A source and 5 A sink peak current per channel. Higher gate drive current charges and discharges the MOSFET or IGBT gate capacitance faster, reducing switching transition times and therefore switching losses. For a SiC MOSFET with 10 nC gate charge, 5 A drive current achieves a turn-on transition of approximately 2 ns, enabling switching frequencies of 100 kHz or more in automotive DC-DC converter stages with acceptable thermal performance.
What does the reverse current protection feature in UCC27624QDRQ1 protect against?
Reverse current protection prevents current from flowing back from the gate driver output into the supply pin when the output is pulled above the supply voltage by external transients or bootstrap capacitor overvoltage. This is especially important in half-bridge and H-bridge configurations where the switching node can slew rapidly, potentially forward-biasing the output stage and injecting reverse current that could damage the driver. The integrated protection removes the need for a discrete Schottky diode on each output.
How does the Schmitt-trigger input of UCC27624QDRQ1 improve reliability in automotive EMC environments?
Schmitt-trigger inputs add hysteresis between the rising and falling threshold voltages — typically 0.5 V to 1 V — so that slow-rising or noisy PWM signals do not cause multiple output transitions from a single input edge. In automotive ECUs, radiated and conducted EMI from motors, ignition systems, and power converters can corrupt logic signals; the Schmitt-trigger input on UCC27624QDRQ1 ensures that only clean, deliberate PWM transitions trigger the gate driver output, improving system EMC robustness.
Can UCC27624QDRQ1 drive both the high-side and low-side of a synchronous buck converter?
Yes, UCC27624QDRQ1 is a dual-channel driver with a high-side driver output, making it suitable for driving both the high-side and low-side MOSFETs of a synchronous buck converter. In a typical 48 V automotive DC-DC design, the high-side channel uses a bootstrap capacitor supply while the low-side channel is powered from the gate-drive bias rail, and both channels deliver 5 A peak to rapidly switch the power FETs at frequencies of 200 kHz or higher with dead-time controlled by the PWM controller.
