... Undervoltage Lockout • ESD and Short Circuit Protected • Fault Feedback 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 ...

... Pin 3: V+ This is the only external power supply required for the Si9976DY, and must be the same supply used to power the half-bridge it is driving. The Si9976DY powers it’s low-voltage logic, low-side gate driver, and bootstrap/charge pump circuits from self-contained voltage regulators which require only a ...

... DETAILED DESCRIPTION Power On Conditioning Bootstrap-type floating supplies require that the bootstrap capacitor be charged at power on. Si9976DY, this is accomplished by pulsing the IN line low with the EN line held high, thus turning on the low-side MOSFET and providing the charging path for the capacitor. Operating Voltage ...
