Ultra-High CMTI Isolated Gate Drivers
Integrated Isolation with High CMTI to Improve Robustness for SiC Gate Driver
The MAX22700–MAX22702 are a family of 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 Maxim’s proprietary process technology. The devices feature variants with output options for gate driver common pin GNDB (MAX22700), Miller clamp (MAX22701), and adjustable undervoltage-lockout UVLO (MAX22702). In addition, 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 in the family feature isolation for a withstand voltage rating of 3kVRMS for 60 seconds.
All devices 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.

Himalaya uSLIC Power Modules
Himalaya uSLIC™ DC-DC power modules use the latest semiconductor process and packaging technology to deliver the smallest solution size, while minimizing temperature rise and total cost-of-ownership. The family offers a broad selection of products addressing diverse input voltage requirements from 2.9V to 5.5V and 4.5V to 24V/42V/60V, with output current capability ranging from 100mA to 2A in an ultra-small package. Compared to discrete-style implementations, the Himalaya uSLIC power modules shrink the power supply solution size by up to 2.25x, creating a micro-sized system-level IC (uSLIC). This is achieved by integrating a synchronous wide-input Himalaya buck converter—which includes built-in FETs, compensation, and additional functions—with an inductor.
The combination of these components results in ultra-small power modules that can be used in a wide variety of applications, from low-voltage battery applications to large factory automation applications. These uSLIC modules enable power supplies to be designed into very tight space-constrained areas and enable reliable and robust power conversion. The modules comply with the JESD22-B103/B104/B111 mechanical standard as well as the CISPR 22 electromagnetic interference (EMI) standard, helping to improve the first-time success rate for EMI certification of your end products.
