Ultra-High CMTI Isolated Gate Drivers

Description

The MAX22700–MAX22702 are a family of single-channel isolated gate drivers with ultra-high common-mode transient immunity (CMTI) of 300kV/µs (typ). TThe devices are 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. The devices feature variants with output options for gate driver common pin GNDB (MAX22700), Miller Clamp (MAX22701), and adjustable undervoltagelockout UVLO (MAX22702). In addition, variants are offered as differential (D versions) or single-ended (E versions) inputs. All devices have integrated digital galvanic isolation using Maxim’s proprietary process technology. The MAX22700–MAX22702 feature isolation for a withstand voltage rating of 3kVRMS(narrow SOIC package) or 5kVRMS(wide SOIC package) 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.The MAX22700 and the MAX22702 have a maximum RDSONof 1.25Ω for the low-side driver, and the MAX22701 has an RDSONof 2.5Ω for the low-side driver. All devices have a maximum RDSONof 4.5Ω for the high-side driver. See the Ordering Information for suffixes associated with each option.The MAX22700–MAX22702 are available either in an 8-pin wide-body SOIC package with 8mm creepage and clearance, or in a smaller 8-pin narrow-body SOIC package with 4mm of creepage and clearance. The narrow SOIC package material has a minimum comparative tracking index (CTI) of 600, which gives it a group I rating in creepage tables, while the wide SOIC package material has a minimum CTI of 400, which gives it a group II rating in creepage tables. All devices are rated for operation at ambient temperatures of -40°C to +125°C.Design Solution: Choose a High CMTI Gate Driver That Cuts Your SiC Switch Dead-Time ›ApplicationsIsolated Gate Driver for InvertersMotor DrivesUPS and PV Inverters
