This single-channel isolated gate driver delivers 3 A class drive with an active Miller clamp, adjustable desaturation detection, and soft turn-off for IGBTs and SiC or Si MOSFETs. It uses reinforced galvanic isolation rated 5.7 kVrms and supports a 3 V to 6.5 V input-side supply with 3.3 V or 5 V CMOS-compatible logic. Output characteristics include 3.8 A source current, 2.5 A sink current, 244 ns turn-on delay, and 236 ns turn-off delay. The device is housed in a PG-DSO-16-33 package with more than 8 mm creepage and clearance and operates at ambient temperatures up to 125 °C. Safety approvals include UL 1577 recognition and IEC 60747-17 reinforced insulation certification.
