IXDN430 / IXDI430 / IXDD430 / IXDS430
30 Amp Low-Side Ultrafast MOSFET / IGBT Driver
General Description
Features
• Built using the advantages and compatibility
of CMOS and IXYS HDMOSTM processes
• Latch-UpProtected
• High Peak Output Current: 30A Peak
• Wide Operating Range: 8.5V to 35V
• Under Voltage Lockout Protection
• Ability to Disable Output under Faults
• High Capacitive Load
TheIXDN430/IXDI430/IXDD430/IXDS430arehighspeedhigh
current gate drivers specifically designed to drive MOSFETs
and IGBTs to their minimum switching time and maximum
practical frequency limits. The IXD_430 can source and sink
30A of peak current while producing voltage rise and fall times
of less than 30ns. The input of the drivers are compatible with
TTL or CMOS and are fully immune to latch up over the entire
operating range. Designed with small internal delays, cross
conduction/current shoot-through is virtually eliminated in all
configurations. Their features and wide safety margin in

Drive Capability: 5600 pF in <25ns
• Matched Rise And Fall Times
• Low Propagation Delay Time
• LowOutputImpedance
• LowSupplyCurrent
The IXD_430 incorporates a unique ability to disable the output
under fault conditions. The standard undervoltage lockout is at
12.5V which can also be set to 8.5V in the IXDS430SI. When a
logical low is forced into the Enable inputs, both final output
stage MOSFETs (NMOS and PMOS) are turned off. As a
result, the output of the IXDD430 enters a tristate mode and
enables a Soft Turn-Off of the MOSFET when a short circuit is
detected. This helps prevent damage that could occur to the
MOSFET if it were to be switched off abruptly due to a dv/dt
over-voltagetransient.
