Importing Modules and Chips

Using the tscircuit TI Library

Overview​

The @tsci/tscircuit.ti package exports:

  • chip components such as BQ24074, INA237, and TPS22919
  • functional modules such as BatteryManagement_BQ24074, LoadSwitch_TPS22919, and PowerMonitor_INA237

Use a chip when you want to wire the part yourself. Use a functional module when you want a prebuilt TI reference design.

Install​

bun add @tsci/tscircuit.ti

Import a Chip​

import { BQ24074 } from "@tsci/tscircuit.ti";

If you want a specific package, import that package name directly:

import { BQ24074RGTR } from "@tsci/tscircuit.ti";

Some chip families also support footprintVariant:

import { BQ24074 } from "@tsci/tscircuit.ti";

export default () => <BQ24074 name="U1" footprintVariant="vqfn_16_ep_3x3" />;

Place a Chip​

import { TPS22919 } from "@tsci/tscircuit.ti"

  export default () => (
    <board width="18mm" height="14mm">
      <TPS22919 name="U1" />
    </board>
  )

Wire a Chip​

import { TPS22919 } from "@tsci/tscircuit.ti"

  export default () => (
    <board width="24mm" height="16mm">
      <TPS22919
        name="U1"
        noConnect={["NC", "QOD"]}
        connections={{
          IN: "net.VIN",
          GND: "net.GND",
          ON: "net.VIN",
          OUT: ".R_LOAD > .pin1",
        }}
      />

      <resistor
        name="R_LOAD"
        resistance="1k"
        footprint="0402"
        connections={{ pin2: "net.GND" }}
      />
    </board>
  )

In this example:

  • IN and ON are tied to VIN
  • OUT drives the external load resistor
  • GND is tied to ground
  • NC and QOD are intentionally left unconnected

Use a Functional Module​

import { LoadSwitch_TPS22919 } from "@tsci/tscircuit.ti"

  export default () => (
    <board width="24mm" height="16mm">
      <LoadSwitch_TPS22919 name="POWER_SWITCH" />
    </board>
  )

If you want a more complete reference design, use one of the functional module exports instead of wiring the chip from scratch.
