Product Summary

The SI9976DY is an integrated driver for an n-channel MOSFET half-bridge. Schmitt trigger inputs provide logic signal compatibility and hysteresis for increased noise immunity. An internal low-voltage regulator allows the device to be powered directly from a system supply of 20 to 40 V. Both half-bridge n-channel gates are driven directly with low-impedance outputs. Addition of one external capacitor allows an internal circuit to level shift both the power supply and logic signal for the half-bridge high-side n-channel gate drive. The applications of the SI9976DY are Power Supplies, Motor Drives, Office Automation, Computer Peripherals, Industrial Controllers, Robotics and Medical Equipment.
