Half-bridge gate driver with 3 A peak drive and 120 V bootstrap ceiling
The Texas Instruments UCC27201DRMR is a high-frequency half-bridge gate driver designed for N-channel MOSFETs in synchronous buck, full-bridge, and motor-drive stages. The bootstrap supply supports a high-side voltage up to 120 V, suiting it for 48 V to 72 V bus architectures common in telecom rectifiers, battery-powered traction inverters, and industrial power supplies. The two driver channels are independent with non-inverting inputs, so the same part handles both high-side and low-side FETs without external level shifting.
Supply range, logic thresholds, and temperature grade
The driver operates from an 8 V to 17 V bias supply, covering the 12 V rail typical in industrial control and automotive auxiliary systems. In a motor-drive or power-supply environment where ambient may reach 85°C, the 140°C junction ceiling provides headroom for self-heating from the 3 A gate charge pulses.
Package, footprint, and sourcing posture
The UCC27201DRMR is supplied in an 8-VDFN exposed-pad package (8-VSON, 4x4 mm).
