Isolated gate driver offers RDS(ON) of 2.5Ohms

The first of the MAX22700-MAX22702 family of single-channel isolated gate drivers with ultra-high common-mode transient immunity (CMTI), the MAX22701E drives silicon-carbide (SiC) or gallium nitride (GaN) transistors in various inverter or motor control applications.

The device features single-ended inputs with a Miller clamp output and transfers digital signals between circuits with different power domains.

It offers an R_DS(ON) of 2.5Ohms for the low-side driver and maximum R_DS(ON) of 4.5Ohms for the high-side driver.

The MAX2270x family ICs' ultra-high CMTI of 300 kV/μs (typ) and low propagation delay skew making them ideal for use with GaN and SiC FETs in uninterruptible power supplies (UPS), photovoltaic inverters, and motor drives.

All devices have integrated digital galvanic isolation using Maxim's proprietary process technology.

All of the devices in the MAX22700-MAX22702 family are available in an 8-pin, narrow-body SOIC package with 4 mm of creepage and clearance.
