DESCRIPTION:
The SCT52243 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 SCT52243 suitable for high frequency power converter application. The SCT52243 features wide input hysteresis that is compatible for TTL low voltage logic. The SCT52243has the capability to handle negative input down to -5V, which increases the input noise immunity. The SCT52243 has very low quiescent current that reduces the stand-by loss in the power converter. The each channel driver adopts non-overlap driver design to avoid the shoot-through of output stage. The two channels INA and INB have critical delay matching and artificial dead time implemented in output stage, which enable stackableoutput available when the system needs higher driving capability.The SCT52243 features 170°C thermal shut down. TheSCT52243 is available in SOP-8 package.
