Isolated, 4 A Dual-Channel Gate Driver Enhanced Product ADuM3221-EP FEATURES APPLICATIONS 4 A peak output current Isolated synchronous dc-to-dc converters Precise timing characteristics MOSFET/IGBT gate drivers 60 ns maximum isolator and driver propagation delay GENERAL DESCRIPTION 5 ns maximum channel to channel matching High junction temperature operation: 125°C
The ADuM3221-EP1 is an isolated, 4 A dual-channel gate driver
3.3 V to 5 V input logic
based on the Analog Devices, Inc., iCoupler® technology.
7.6 V to 18 V output drive
Combining high speed CMOS and monolithic transformer
Undervoltage lockout (UVLO) at 7.0 V V
technology, this isolation component provides outstanding
DD2 Thermal shutdown protection at >150°C
performance characteristics superior to the alternatives, such as the
Default low output
combination of pulse transformers and gate drivers.
High frequency operation: dc to 1 MHz
The ADuM3221-EP provides digital isolation in two independent
CMOS input logic levels
isolation channels. It has a maximum propagation delay of 60 ns
High common-mode transient immunity: 25 kV/µs
and 5 ns channel to channel matching. In comparison to gate
Safety and regulatory approvals
drivers that employ high voltage level translation methodologies,
UL recognition
the ADuM3221-EP offers the benefit of true, galvanic isolation
2500 V rms for 1 minute per UL 1577
between the input and each output, enabling voltage translation
CSA Component Acceptance Notice 5A (pending)
across the isolation barrier. The ADuM3221-EP allows both
VDE certificate of conformity (pending)
outputs to be on at the same time. This device offers a default
DIN V VDE V 0884-10 (VDE V 0884-10):2006-12
output low characteristic as required for gate drive applications.
VIORM = 560 V peak Small footprint and low profile
The ADuM3221-EP operates with an input supply voltage ranging
Narrow-body, RoHS compliant, 8-lead SOIC
from 3.0 V to 5.5 V, providing compatibility with lower voltage
4.9 mm × 6 mm × 1.55 mm
systems. The outputs of the ADuM3221-EP can be operated at supply voltages from 7.6 V to 18 V.
