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
