DESCRIPTION  
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. 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. The Si9976DY is available in the  
14-pin SOIC (surface mount) package, specified to operate  
over the industrial (-40 to 85°C) temperature range.
