马达驱动高低边驱动

双通道下管IGBT/MOSFET栅极驱动器 SCT52241 可替代IR4428S，UCC27525A，MAX5057/MAX628，ISL89165，TC4428M

The SCT52241 is a wide supply, dual channel, high
speed, low side gate drivers for both power MOSFET
and IGBT. Each channel can source and sink 4A peak
current along with rail-to-rail output capability. The 24V
power supply rail enhances the driver output ringing
endurance during the power device transition.
The minimum 13ns input to output propagation delay
enables the SCT52241 suitable for high frequency
power converter application.
The SCT52241 features wide input hysteresis that is
compatible for TTL low voltage logic. The SCT52241
has the capability to handle negative input down to -5V,
which increases the input noise immunity.
The SCT52241 has very low quiescent current that
reduces the stand-by loss in the power converter. The
SCT52241 each channel driver adopts non-overlap
driver design to avoid the shoot-through of output
stage.
The SCT52241 features 170°C thermal shut down. The
SCT52241 is available in SOP-8 package
