What it represents
A diode-capacitor arrangement used to supply a floating high-side gate-driver circuit under documented switching conditions.
On a schematic, identify the bootstrap diode, capacitor and switching-node return and trace the driver's floating supply and charging path. Keep the component tag and signal/reference names consistent across the control drawing, terminal schedule and device documentation.
A bootstrap circuit depends on its charging opportunity; it is not a continuous independent isolated DC supply.
The preview is an independently drawn educational functional reference. Add the selected component’s actual power pins, terminal numbers, timing or analogue reference details when producing a construction drawing.
How to read it
- Identify the bootstrap diode, capacitor and switching-node return.
- Trace the driver's floating supply and charging path.
Information to show or reference
- Label the bootstrap diode, capacitor and switching-node return.
- Cross-reference the driver's floating supply and charging path.
- Add the selected device or circuit documentation revision, power/reference connections and project signal convention.
A distinction that matters
A bootstrap circuit depends on its charging opportunity; it is not a continuous independent isolated DC supply.
