Half-bridge driver for 48 V to 72 V automotive bus rails
The Texas Instruments UCC27201AQDMKRQ1 is an automotive-grade, AEC-Q100 qualified half-bridge gate driver for N-channel MOSFETs. It delivers 3 A peak source and sink current from an 8 V to 17 V supply rail, with a bootstrap high-side rating of 120 V. The independent channel architecture lets each output be controlled separately, which simplifies dead-time insertion in hard-switched bridge topologies.
3 A peak drive and 8 ns edges — sizing the gate drive budget
The 3 A peak source and sink current, combined with 8 ns rise and 7 ns fall times (typical), means the driver can charge and discharge a MOSFET gate capacitance within the switching period.
140°C junction and 120 V bootstrap — deployment envelope
The -40°C to 140°C junction temperature range exceeds the standard automotive limit, suiting this driver for under-hood environments and high-ambient motor-drive compartments. The 120 V maximum bootstrap voltage supports nominal DC-link rails with derating margin.
