DESCRIPTION
The Si9976 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 volts. 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. An internal
