MAXIM INTEGRATED MAX22700–MAX22702 Isolated Gate Drivers | New Product Brief
This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.
Maxim Integrated’s MAX22700 to MAX22702 family of isolated gate drivers offer ultra-high common mode transient immunity and are ideal for driving silicon carbide and gallium nitride transistors in inverter and motor drive applications.
CMT is rated at 300kV/µs, and the parts provide robust galvanic isolation between the input and output. The family includes a variety of output options, and each is available with single-ended or differential input variants. Propagation delay is matched to within 2ns from part-to-part at 25°C and to within 5ns over the full -40°C to +125°C operating range, minimizing transistor dead time and increasing efficiency. The gate drivers support pulses as short as 20ns and have minimum distortion.
All parts in the family are housed in a narrow body SOIC package that provides 4mm of creepage and clearance.
