UCC27624QDRQ1

UCC27624QDRQ1 is a Texas Instruments dual, high-speed gate-driver IC. It provides two independent gate-drive channels that can drive two N-channel MOSFETs (e.g., in a half-bridge or two separate switches) with fast rise/fall times and high peak sourcing/sinking current. The device includes logic-compatible inputs and built-in protections such as undervoltage lockout, shoot-through prevention with dead-time control, and fault handling. It’s intended for switch-mode power supplies, DC-DC converters, motor drivers, and automotive power electronics. The QDRQ1 suffix denotes the specific package/variant of this device.

UCC27624QDRQ1 is a dual, bootstrapped, high-side/low-side gate-driver designed for two NMOS devices or two half-bridges in automotive/industrial power stages. Key features:
- Dual gate-driver channels: independent HO (high-side) and LO (low-side) outputs.
- Bootstrapped high-side drive: enables driving the high-side MOSFET in each half-bridge.
- Independent inputs: one control per channel with a dedicated enable/shutdown input.
- Protections: undervoltage lockout (UVLO), overcurrent/short-circuit protection, and thermal protection.
- Shoot-through prevention: dead-time control between channels to prevent cross-conduction.
- Fault/status reporting: fault/flag outputs to indicate UVLO, overcurrent, or thermal events.
- Drive capability: strong peak source/sink for fast switching (typical gate-drive performance).
- Automotive-grade: AEC-Q100 qualified, suitable for -40°C to 125°C applications.
- Noise and transient tolerance: designed for switching noise in automotive/industrial environments.
- Packaging: available in compact QFN/SO variants suitable for densely populated boards.
Note: For exact electrical specs (voltage ranges, UVLO thresholds, dead-time, and package options), consult the TI datasheet for UCC27624QDRQ1.

An 8-pin QFN package (QFN-8), RoHS-compliant.
