New Maxim MAX22702E

On April 27th 2020, Maxim Integrated officially released MAX22702E for mass production – an Ultra-High CMTI Isolated Gate Driver.

The new MAX22702E is a member of MAX22700–MAX22702 family: Single-chan­nel isolated gate drivers with ultra-high common-mode transient immunity (CMTI) of 300kV/μs (typ). The devices of this family are designed to drive silicon-carbide (SiC) or gallium-nitride (GaN) transistors in various inverter or motor control applications. They come with integrated digital galvanic isolation using Maxim’s proprietary process tech­nology. MAX22702E device configuration is offering single-ended input and adjustable undervoltage-lockout (UVLO) output. Other configurations with different input (single-ended and differential) and output options (GNDB, Miller clamp and UVLO) are available in the MAX22700-MAX22702 family as well. MAX22702E, as well as all other products of the family, features isolation for a withstand voltage rating of 3kV RMS for 60 seconds.

In addition, all devices of the family support a minimum pulse width of 20ns with a maximum pulse width distortion of 2ns. The part-to-part propagation delay is matched within 2ns (max) at +25°C ambient temperature, and 5ns (max) over the -40°C to +125°C operating temperature range. This feature reduces the power transistor’s dead time, thus improving overall efficiency.

MAX22702E have a maximum RDS(ON) of 1.25Ω for the low-side driver and 4.5Ω for the high-side driver. It can be used to drive SiC or GaN FETs with different output gate drive circuitry and B-side supply voltages. It is offered in 8-pin narrow-body SOIC package with 4mm of creepage and clearance. Operating ambient temperature range is from -40°C to +125°C.

Target application areas for MAX22702E Isolated Gate Drivers are:

  • Inverters
  • Motor Drives
  • UPS and PV Inverters

For customer evaluation of the MAX22702E, Maxim Integrated offers Evaluation Kits MAX22702EVKIT# that represent a proven design, fully assembled and tested.
