Preliminary Technical Information
IXDD514 / IXDE514
14 Ampere Low-Side Ultrafast MOSFET Drivers
with Enable for fast, controlled shutdown
Features
General Description
• Built using the advantages and compatibility
of CMOS and IXYS HDMOSTM processes
• Latch-UpProtectedoverentireOperatingRange
• High Peak Output Current: 14A Peak
• Wide Operating Range: 4.5V to 30V
• -55°Cto+125°CExtendedOperating
Temperature
• Ability to Disable Output under Faults
• High Capacitive Load
Drive Capability: 15nF in <30ns
• Matched Rise And Fall Times
• Low Propagation Delay Time
• LowOutputImpedance
TheIXDD514andIXDE514arehighspeedhighcurrentgate
drivers specifically designed to drive the largest IXYS
MOSFETs & IGBTs to their minimum switching time and
maximum parctical frequency limits. The IXDD514 and
IXDE514 can source and sink 14 Amps of Peak Current
while producing voltage rise and fall times of less than
30ns. The inputs of the Drivers are compatible with TTL or
CMOS and are virtually immune to latch up over the entire
operatingrange! Patented*designinnovationseliminate
crossconductionandcurrent"shoot-through". Improved
speedanddrivecapabilitiesarefurtherenhancedbyvery
quick & matched rise and fall times.
TheIXDD514andIXDE514incorporateauniqueabilityto
disable the output under fault conditions. When a logical
low is forced into the Enable input, both final output stage
MOSFETs, (NMOS and PMOS) are turned off. As a result,
the output of the IXDD514 or IXDE514 enters a tristate
modeandachievesaSoftTurn-OffoftheMOSFET/IGBT
when a short circuit is detected. This helps prevent dam-
age that could occur to the MOSFET/IGBT if it were to be
switchedoffabruptlyduetoadv/dtover-voltagetransient.
