What it represents
A packaged power-switch arrangement forming one half-bridge switching leg.
On a schematic, identify positive/negative DC terminals, switching midpoint and separate gate/return pins and trace the converter phase leg and driver interfaces. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
The module topology does not define its ratings or package terminal order; the selected module drawing remains authoritative.
Terminal letters describe electrical roles, not package pin numbers. Check the selected public datasheet for the actual pin assignment, polarity and any internally connected terminals before completing the drawing.
How to read it
- Identify positive/negative DC terminals, switching midpoint and separate gate/return pins.
- Trace the converter phase leg and driver interfaces.
Information to show or reference
- Label positive/negative DC terminals, switching midpoint and separate gate/return pins.
- Cross-reference the converter phase leg and driver interfaces.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.
A distinction that matters
The module topology does not define its ratings or package terminal order; the selected module drawing remains authoritative.
