MAX22700D–MAX22702D
MAX22700E–MAX22702E
Ultra-High CMTI Isolated Gate Drivers
General Description
Benefits and Features
The MAX22700–MAX22702 are a family of single-channel
isolated gate drivers with ultra-high common-mode tran-
sient 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 appli-
cations 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 undervoltage-
lockout UVLO (MAX22702). In addition, variants are of-
fered as differential (D versions) or single-ended (E ver-
sions) inputs. All devices have integrated digital galvanic
isolation using Maxim’s proprietary process technology.
The MAX22700–MAX22702 feature isolation for a with-

● Precision UVLO
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 re-
duces the power transistor’s dead time, thus improving
overall efficiency.
● Options to Support a Broad Range of Applications
• 3 Output Options: GNDB, Miller Clamp, or
Adjustable UVLO
• 2 Input Configurations: Single-Ended with Enable
(E versions) or Differential (D versions)
Safety Regulatory Approvals
● UL According to UL1577
● cUL According to CSA Bulletin 5A
● VDE 0884-11 Basic Insulation (Wide SOIC) (Pending)
The MAX22700 and the MAX22702 have a maximum
R
of 1.25Ω for the low-side driver, and the
DSON
MAX22701 has an R
of 2.5Ω for the low-side driver.
DSON
All devices have a maximum R
of 4.5Ω for the high-
DSON
side driver. See the Ordering Information for suffixes as-
sociated 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 pack-
age with 4mm of creepage and clearance. The narrow
SOIC package material has a minimum comparative track-
ing 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.
Applications
● Isolated Gate Driver for Inverters
● Motor Drives
● UPS and PV Inverters
