# Fuse

## Parameters

<ParamField path="fuse_type" type="dimensionless" />

<ParamField path="response_type" type="dimensionless" />

<ParamField path="trip_current" type="ampere" />

## Interfaces

<ParamField path="unnamed[0]" type="Electrical" />

<ParamField path="unnamed[1]" type="Electrical" />

## Global Attributes

These attributes are available to all modules and interfaces in a design.

<ParamField path="lcsc_id" type="str">
  Assign the LCSC ID of the module.

  If set, this will tell the picker to select that part from LCSC for this block.
</ParamField>

<ParamField path="manufacturer" type="str">
  This module's manufacturer name, as a string.

  Only exact matches on the manufacturer's name will be found by the picker.
  It's recommended to fill this information based on what `ato create component`
  provides.
</ParamField>

<ParamField path="mpn" type="str">
  This module's manufacturer part number, as a string.

  For the picker to select the correct part from the manufacturer,
  this must be set.
</ParamField>

<ParamField path="package" type="str">
  The package of the module.

  This drives which components can be selected, and what footprint is used.

  Must exactly match a known package name.
</ParamField>

<ParamField path="exclude_from_bom" type="bool" />

<ParamField path="override_net_name" type="str">
  When set on an interface, this will override the net name of the interface.

  This is useful for renaming nets which are automatically generated.
</ParamField>

<ParamField path="required" type="bool">
  Only for ModuleInterfaces.
  If set to `True`, require that interface is connected to something outside
  of the module it's defined in.
</ParamField>

<RequestExample>
  ```ato Basic Usage theme={null}
  import Fuse, ElectricPower

  fuse = new Fuse
  fuse.trip_current = 2A +/- 10%
  fuse.fuse_type = Fuse.FuseType.NON_RESETTABLE
  fuse.response_type = Fuse.ResponseType.FAST
  fuse.package = "1206"

  # Connect fuse in series with power supply
  power_input = new ElectricPower
  protected_power = new ElectricPower

  # Fuse protects the circuit from overcurrent
  power_input.hv ~> fuse ~> protected_power.hv
  power_input.lv ~ protected_power.lv

  # For resettable fuse (PTC)
  ptc_fuse = new Fuse
  ptc_fuse.trip_current = 500mA +/- 20%
  ptc_fuse.fuse_type = Fuse.FuseType.RESETTABLE
  ptc_fuse.response_type = Fuse.ResponseType.SLOW

  # Common applications: USB power protection, battery protection
