MAX22700E-MAX22702E General 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). The devices
are designed to drive silicon-carbide (SiC) or galliumnitride (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.
The MAX22700 and the MAX22702 have a maximum
RDSON of 1.25Ω for the low-side driver, and the MAX22701 …
