MAX22700-MAX22702 Isolated Gate Drivers

Analog Devices Inc. MAX22700-MAX22702 Isolated Gate Drivers are a family of single-channel isolated gate drivers with ultra-high common-mode transient immunity (CMTI) of 300kV/μs (typical). The devices are designed to drive silicon-carbide (SiC) or gallium-nitride (GaN) transistors in various inverter or motor control applications. All devices have integrated digital galvanic isolation using Maxim’s proprietary process technology. The drivers feature variants with output options for gate driver common pin GNDB (MAX22700), Miller Clamp (MAX22701), and an adjustable under-voltage-lockout UVLO (MAX22702). Also, variants are offered as differential (D versions) or single-ended (E versions) inputs. These devices transfer digital signals between circuits with different power domains. All of the devices in the family feature isolation for a withstand voltage rating of 3kV_RMS for 60 seconds.
