Half-bridge gate driver for automotive power stages
The Texas Instruments UCC27712QDRQ1 is an automotive-grade half-bridge gate driver qualified to AEC-Q100, designed to drive both N-channel MOSFETs and IGBTs in independent-channel configurations. It integrates a bootstrap diode rated for 600 V high-side voltage, making it suitable for motor drives, DC-DC converters, and inverter stages in under-hood and chassis-domain automotive systems.
10V to 20V supply — matches standard automotive rails
The supply voltage range spans 10 V to 20 V, covering the nominal 12 V battery bus and the boosted 15 V to 18 V rails often used for IGBT gate drive in traction inverters. The 1.8 A source and 2.8 A sink peak output current deliver the gate charge needed for fast switching transitions without excessive drive losses. Rise and fall times are 16 ns and 10 ns typical, respectively, which keeps cross-conduction dead-time manageable in hard-switched topologies.
