Tpmt5510ipb805 - Diagram
Before drawing the diagram, verify the component specifications to ensure it suits your design.
To draw the schematic, you must understand the pin configuration. The IPB package typically follows a standard 4-pin layout for Power MOSFETs with sense capabilities.
Standard IPB (DIP-4) Pinout:
| Pin Number | Name | Function | | :--- | :--- | :--- | | 1 | Source | Current input (connected to Vcc rail). | | 2 | Drain | Current output (connected to Load). | | 3 | Gate | Control voltage input (driven by controller IC). | | 4 | Source Sense | Kelvin connection for accurate current sensing. | tpmt5510ipb805 diagram

To appreciate the integrated diagram, compare it with a discrete IGBT design:
| Feature | Discrete IGBT + Gate Driver | TPMT5510IPB805 (Integrated) | | :--- | :--- | :--- | | Block Diagram Complexity | 50+ components (optocouplers, resistors, BJTs) | Single module with internal logic | | Protection Circuit | External desaturation detection | Internal comparator (shown in diagram) | | Layout Parasitics | High (long traces) | Low (optimized internal bonding) | | Thermal Diagram | Requires 6 separate heatsinks | Single flat baseplate | To draw the schematic, you must understand the
The thermal diagram in the TPMT5510IPB805 datasheet shows the junction-to-case thermal resistance (Rth(j-c)) for the IGBT and diode, which is critical for heatsink sizing.
The VUB, VVB, VWB pins (high-side floating supplies) must be powered via external bootstrap circuits. The internal diagram shows that each high-side IGBT’s gate driver draws current from its respective bootstrap capacitor (e.g., between VUB and VS/U-phase output).
