GENERAL DESCRIPTION
The ADuM4136 is a single-channel gate driver specifically
optimized for driving insulated gate bipolar transistors (IGBTs).
Analog Devices, Inc., iCoupler® technology provides isolation
between the input signal and the output gate drive.
Operation with unipolar or bipolar secondary supplies is
possible, allowing negative gate drive if needed.
The Analog Devices chip scale transformers also provide isolated
communication of control information between the high voltage
and low voltage domains of the chip. Information on the status
of the chip can be read back from dedicated outputs. Control of
resetting the device after a fault on the secondary side is
performed on the primary side of the device.
Integrated onto the ADuM4136 is a desaturation detection
circuit that provides protection against high voltage short-
circuit IGBT operation. The desaturation protection contains
noise reducing features such as a 312 ns (typical) masking time
after a switching event to mask voltage spikes due to initial
turn-on. An internal 537 μA (typical) current source allows low
device count, and the internal blanking switch allows the
addition of an external current source if more noise immunity
is needed.
The secondary UVLO is set to 12 V with common IGBT
threshold levels taken into consideration.
