MAX2270x Ultra-High CMTI Isolated Gate Drivers

Analog Devices Inc. MAX2270x Ultra-High CMTI Isolated Gate Drivers are single-channel isolated gate drivers with ultra-high common-mode transient immunity (CMTI) of 300kV/μs (typ). 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 ADI’s proprietary process technology. The devices feature variants with output options for gate driver common pin GNDB (MAX22700), Miller clamp (MAX22701), or 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 feature isolation for a withstand voltage rating of 3kV_RMS for 60 seconds.
