IGD515EI Block Diagram

The IGD515EI block diagram represents an advanced gate driver integrated circuit designed for efficient and reliable operation of insulated gate bipolar transistors (IGBTs) or other power switching devices. The circuit integrates features such as voltage monitoring, protection logic, and electrical isolation, ensuring safe and stable operation under various conditions.

The left section of the diagram includes the input signal processing components. Pins like INPUT, INV, and SDOSA are connected to the interface logic, which interprets and conditions the input signals for proper driver operation. A built-in 5V regulator provides stable power to the logic circuitry. The Voltage Monitoring and Vce Monitoring blocks further ensure safe voltage levels by preventing overvoltage or undervoltage conditions.

The central Interface Logic block processes incoming signals, coordinating with the Protection Logic and Timing Control to ensure proper device operation. These blocks provide functions such as soft switching, short-circuit protection, and fault indication to enhance the safety and performance of the circuit.

The right section houses the high-power driving stage, including the Driver, which generates the required gate signals for the connected IGBT or MOSFET. Pins like G, E, and Cb are connected to the gate and emitter terminals of the switching device. The Protection Logic works in tandem with the driver to disable the gate signal during fault conditions.

The lower section highlights the electrical isolation achieved via a transformer-based PWM controller. This isolation ensures that the high-voltage and low-voltage sections remain electrically separated, safeguarding sensitive circuitry. The isolated power supply (+Viso) powers the output stage, with pins like COM and Cs managing ground reference and current sensing.
