Maxim Releases Isolated Silicon Carbide Gate Driver, Provides Industry's Best Power Efficiency, Extends System Uptime

MAX22701E triples CMTI performance and reduces overall system energy consumption by 30%, effectively extending system runtime

Beijing, China—December 18, 2019—Maxim Integrated Products, Inc (NASDAQ: MXIM) announces the launch of the MAX22701E isolated gate driver, helping designers of high-voltage / high-power systems increase power efficiency by 4%, outperforming competing products; Reduce energy consumption and carbon emissions by 30%. Driver ICs are optimized for switching power supplies for industrial communication systems. Typical applications include solar power inverters, motor drives, electric vehicles, energy storage systems, uninterruptible power supplies, data farms, and other high-power / high-efficiency power supplies.

Currently, many switching power supplies use wide band gap silicon carbide (SiC) transistors to improve power supply efficiency and transistor reliability. However, the transient characteristics of the high switching frequency will produce large noise, affect the normal operation of the system or require additional measures to suppress interference. The MAX22701E provides the industry's highest common-mode transient suppression (CMTI): 300kV / µs (typical), providing industry-leading reliability. Its CMTI index is three times higher than its closest competitor, significantly extending the system uptime. The industry's lowest transmission delay (typically 35ns, which is 2 times lower than the nearest competing product), and the best matching of the transmission delay between high-side and low-side gate drivers (up to 5ns, which is lower than the nearest competing product) 5 times), which helps to reduce the dead time of the transistor, thereby improving the power supply efficiency by 4 percentage points. When the efficiency reaches 90% or more, each percentage point increase in efficiency can reduce power consumption by about 10%. For example, increasing the efficiency from 90% to 94% will reduce power consumption by 30% to 40% (the wasted power is reduced from 10% to 6%). The MAX22701E is available in an 8-pin narrow SOIC package (3.90mm x 4.90mm) and operates over the -40 ° C to + 125 ° C extended temperature range.

Key advantages:

Reduce energy consumption: The transmission delay consistency between devices is improved by 5 times (maximum 5ns), which greatly reduces the dead time and energy consumption.

Extend the system uptime: CMTI is increased by 3 times (typical value is 300kV / µs), minimizing the common-mode transient between the input and output, and extending the system uptime in a noisy environment.
