Instructions for Use:
- Power Supply Connection: Connect Vcc to the high-side power supply and Vdd to the logic power supply. Ensure both supplies are within their specified operating ranges.
- Ground Connections: Properly connect all ground pins (COM, Source) to ensure stable operation.
- Input Signal: Apply the control signal to the IN pin. The driver responds to this signal to drive the output MOSFETs.
- Bootstrap Capacitor: For high-side driving, use a bootstrap capacitor connected between the Boot and Source pins.
- Dead-Time Insertion: Implement dead-time between high-side and low-side switching to prevent shoot-through current.
- Heat Dissipation: Keep the junction temperature within limits by providing adequate heat sinking if necessary.
- Protection Circuits: Utilize external protection circuits like flyback diodes for inductive loads.
- Signal Integrity: Ensure short and impedance-matched PCB traces for high-frequency signals to minimize noise and interference.
