The **IRS2336DJPBF** is a high-voltage, high-speed power MOSFET and IGBT driver with three independent high-side and low-side referenced output channels. It is primarily used for three-phase motor drive applications. --- ## 1. Core Technical Specifications The following table highlights the primary electrical characteristics of the IRS2336DJPBF: | Parameter | Specification | | :--- | :--- | | **Configuration** | 3-Phase Gate Driver (6 Outputs) | | **Max Offset Voltage ($V_{offset}$)** | 600V | | **Output Source/Sink Current** | 200mA / 350mA | | **Gate Drive Supply ($V_{CC}$)** | 10V to 20V | | **Logic Input Compatibility** | 3.3V, 5V, and 15V | | **Package Type** | PLCC-44 | | **Deadtime (Typical)** | 290 ns (Internal) | --- ## 2. Key Integrated Features This IC is designed to reduce component count by integrating several safety and logic functions: ### A. Integrated Bootstrap Functionality The "D" in the part number signifies integrated **bootstrap diodes**. These diodes provide the necessary high-side power supply from the low-side $V_{CC}$, eliminating the need for six external diodes in a typical 3-phase inverter design. ### B. Comprehensive Protection * **Under-Voltage Lockout (UVLO):** Prevents the power transistors from operating in a linear mode (which causes overheating) if the supply voltage is too low. * **Over-Current Protection:** Includes an operational amplifier and a comparator to sense current across a shunt resistor and shut down outputs if a fault is detected. * **Shoot-Through Prevention:** Internal deadtime logic ensures that the high-side and low-side switches of the same phase are never "ON" at the same time. ### C. Logic and I/O * **Negative Transient Immunity:** The device is robust against negative voltage spikes ($V_S$ spikes) common in high-speed motor switching. * **Fault Reporting:** A dedicated `FAULT` pin signals the microcontroller if an over-current or under-voltage event occurs. * **Enable Pin:** Allows for a global shutdown of all six gate outputs. --- ## 3. Typical Application Circuit In a standard implementation, the IRS2336DJPBF acts as the bridge between a Microcontroller (MCU) and the Power Stage (IGBTs/MOSFETs). ```text [ Microcontroller ] ----> [ IRS2336D ] ----> [ 3-Phase Inverter ] ----> [ Motor ] (PWM Signals) (Gate Driver) (6x IGBTs/MOSFETs) ``` ### Pin Grouping Logic 1. **HIN1/2/3 & LIN1/2/3:** Logic inputs from the MCU. 2. **HO1/2/3 & LO1/2/3:** Gate drive outputs to the power transistors. 3. **VB1/2/3 & VS1/2/3:** High-side floating supply connections (using bootstrap capacitors). 4. **ITRIP:** Over-current sensing input. --- ## 4. Summary of Advantages * **Space Saving:** The PLCC-44 package and integrated diodes save significant PCB real estate. * **Reliability:** Built-in hardware protection reacts faster than software-based protection in an MCU. * **Versatility:** Compatible with a wide range of power levels due to the 600V offset capability.
