SCT51240TWBR

The SCT51240 is a wide supply, single channel, high speed, low side gate driver for power MOSFET, IGBT, and wide band-gap device such as GaN. The 24V power supply rail enhances the driver output ringing endurance during the power device transition. The capability to switch below 5V power supply makes the SCT51240 work well for the low voltage threshold power device. The SCT51240 can source and sink 4A peak current along with rail-to-rail output driving capability. The minimum 12ns input to output propagation delay enables it suitable for high frequency power converter application. The SCT51240 features wide input hysteresis that is compatible for TTL low voltage logic. The SCT51240 has the capability to handle negative input down to -5V, which enhances the input noise immunity. The IN+ and IN- input provides the flexibility to configure the SCT51240 either as non-inverting or inverting driver. The SCT51240 has very low quiescent current that reduces the stand by power loss in the power converter. The SCT51240 gate driver adopts nonoverlap driver design to avoid the shoot-through of output stage. The SCT51240 features 170°C thermal shut down protection and operates over a wide temperature range -40°C to 150°C. The SCT51240 is available in TSOT23-5L package.
