MAX22700EASA+

Single-channel isolated gate driver with ultra-high common-mode transient immunity (CMTI) of 300KV/μs (typ). The devices is designed to drive silicon-carbide (SiC) or gallium-nitride (GaN) transistors in various inverter or motor control applications with different output gate-drive circuitry and B-side supply voltages. It features variants with output options for gate driver common pin GNDB. Devices has integrated digital galvanic isolation using Maxim’s proprietary process technology. Also features isolation for a withstand voltage rating of 3KVRMS (narrow SOIC package) for 60 seconds. It supports a minimum pulse width of 20ns with a maximum pulse width distortion of 2ns. The MAX22700 has a maximum RDSON of 1.25ohm for the low-side driver. It has a maximum RDSON of 4.5ohm for the high side driver. Applications include isolated gate driver for inverters, motor drives, UPS and PV Inverters.
