TPS2140IPWP Frequently Asked Questions (FAQs)

  • The TPS2140IPWP can sink up to 1.5A of current, but it's recommended to limit it to 1A for reliable operation.
  • To ensure fast switching, make sure to use a low-ESR capacitor (less than 1 ohm) and a short trace length between the capacitor and the device. Also, use a pull-up resistor of around 1k ohm to 4.7k ohm on the EN pin.
  • The EN (enable) pin is used to turn the switch on and off. To turn the switch on, pull the EN pin high (above 1.4V), and to turn it off, pull it low (below 0.4V). The EN pin has an internal pull-down resistor, so if left unconnected, it will default to the off state.
  • No, the TPS2140IPWP is designed as a low-side switch, meaning it can only switch the ground connection of a load. It's not suitable for high-side switching applications.
  • The power dissipation of the TPS2140IPWP can be calculated using the formula: Pd = (VIN - VOUT) x IOUT x Rds(on), where Rds(on) is the on-state resistance of the switch, which is typically around 0.1 ohm.
