SI9910 Adaptive Power MOSFET Driver1

The Si9910 Power MOSFET driver provides optimized gate drive signals, protection circuitry and logic level interface. Very low quiescent current is provided by a CMOS buffer and a high-current emitter-follower output stage. This efficiency allows operation in high-voltage bridge applications with “bootstrap” or “charge-pump” floating power supply techniques..
