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 charge pump replaces leakage current lost in the high-side driver circuit to provide “static” (dc) operation in any output condition. Protection features include an undervoltage lockout, cross-conduction prevention logic, and a short circuit monitor.
