Ultra-High CMTI

Isolated Gate Drivers

General Description

Beneﬁts and Features

● Matching Propagation Delay

The MAX22700–MAX22702 are a family of single-chan-

nel 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 tech-

nology. 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

• 20ns Minimum Pulse Width

• 35ns Propagation Delay at Room Temperature

• 2ns Part-to-Part Propagation Delay Matching at

Room Temperature

• 5ns Part-to-Part Propagation Delay Matching over

-40°C to +125°C Temperature Range

● Precision UVLO

● Options to Support a Broad Range of Applications

• 3 Output Options: GNDB, Miller Clamp, or

Adjustable UVLO

for 60 seconds.

RMS

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.

• 2 Input Conﬁgurations: Single-Ended with Enable

(E versions) or Diﬀerential (D versions)

Applications

● Isolated Gate Driver for Inverters

● Motor Drives

The MAX22700 and the MAX22702 have a maximum

● UPS and PV Inverters

of 1.25Ω for the low-side driver, and the MAX22701

DSON

has an R

Safety Regulatory Approvals

● UL According to UL1577

of 4.5Ω for the high-side driver.

each option.

The MAX22700–MAX22702 can be used to drive SiC or

GaN FETs with different output gate drive circuitry and

B-side supply voltages. See the Typical Operating Circuits

for details.

Ordering Information appears at end of data sheet.

All of the devices in the MAX22700–MAX22702 family

are available in an 8-pin, narrow-body SOIC package with

4mm of creepage and clearance. The package material

has a minimum comparative tracking index (CTI) of 600V,

which gives it a group I rating in creepage tables. All

devices are rated for operation at ambient temperatures

of -40°C to +125°C.
