The SCT52240 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 SCT52240 suitable for high frequency
power converter application.
The SCT52240 features wide input hysteresis that is
compatible for TTL low voltage logic. The SCT52240
has the capability to handle negative input down to -5V,
which increases the input noise immunity.
The SCT52240 has very low quiescent current that
reduces the stand-by loss in the power converter. The
SCT52240 each channel driver adopts non-overlap
driver design to avoid the shoot-through of output
stage. The two channels INA and INB have critical
propagation delay matching and artificial dead time
implemented in output stage, which enable stackable
output available when the system needs higher driving
capability.
The SCT52240 features 170°C thermal shut down. The
SCT52240 is available in SOP-8 and eMSOP-8
package.
