- **Caution**: 

### Q: What is the primary function of a gate driver in power electronics?
**A**: Gate drivers provide the necessary voltage and current signals to control the switching of power transistors (like MOSFETs or IGBTs) in inverter bridges, ensuring efficient and precise power conversion in electronic systems.

### Q: Why is isolation important in gate driver circuits?
**A**: Isolation barriers in gate drivers protect low-voltage control circuits from high-voltage power stages, prevent ground loops, enhance safety, and ensure reliable operation in applications like motor drives and power supplies.

### Q: What protection features are typically included in industrial gate drivers?
**A**: Common protection circuitry includes under-voltage lockout (UVLO), over-current protection, short-circuit protection, thermal shutdown, and dead-time control to prevent shoot-through in half-bridge configurations.
