Isolated Precision Gate Driver, 4.0 A Output Data Sheet ADuM3123 FEATURES GENERAL DESCRIPTION 4.0 A output short-circuit pulsed current
The ADuM31231 is a 4.0 A isolated, single channel driver that
Isolated working voltage
employs Analog Devices, Inc., iCoupler® technology to provide
Secondary side to input side: 537 V
precision isolation. The ADuM3123 provides 3000 V rms
High frequency operation: 1 MHz maximum
isolation in the narrow-body, 8-lead SOIC package. Combining
3.3 V to 5 V input logic
high speed CMOS and monolithic transformer technology,
4.5 V to 18 V output drive
these isolation components provide outstanding performance
Undervoltage lockout (UVLO): 2.8 V VDD1
characteristics superior to alternatives such as the combination
Precise timing characteristics
of pulse transformers and gate drivers.
64 ns maximum isolator and driver propagation delay
The ADuM3123 operates with an input supply ranging from
Complementary metal oxide semiconductor (CMOS) input
3.0 V to 5.5 V, providing compatibility with lower voltage
logic levels
systems. In comparison to gate drivers employing high voltage
High common-mode transient immunity: >25 kV/μs
level translation methodologies, the ADuM3123 offers the
High junction temperature operation: 125°C
benefit of true, galvanic isolation between the input and the
Default low output
output. The output can continuously operate up to 380 V rms
Safety and regulatory approvals (pending)
relative to the input.
UL recognition per UL 1577 3000 V rms for 1 minute SOIC long package
As a result, the ADuM3123 provides reliable control over the
CSA Component Acceptance Notice 5A
switching characteristics of IGBT/MOSFET configurations over
VDE certificate of conformity (pending)
a wide range of positive and negative switching voltages.
