TPS2140IPWPR datasheet by Texas Instruments

TPS2140IPWPR Frequently Asked Questions (FAQs)

• What is the maximum current that can be drawn from the TPS2140IPWPR?
  The maximum current that can be drawn from the TPS2140IPWPR is 2A per channel, but it's recommended to limit the current to 1.5A per channel for reliable operation.
• How do I ensure that the TPS2140IPWPR is properly powered on and off?
  To ensure proper power-on and power-off, make sure to follow the power sequencing guidelines in the datasheet, and use a voltage ramp-up time of at least 1ms to avoid inrush current issues.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to turn the switch on or 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).
• How do I handle thermal management for the TPS2140IPWPR?
  To handle thermal management, ensure good airflow around the device, use a heat sink if necessary, and follow the thermal design guidelines in the datasheet to avoid overheating.
• What are the ESD protection features of the TPS2140IPWPR?
  The TPS2140IPWPR has built-in ESD protection features, including 2kV human-body model (HBM) and 200V machine model (MM) protection, to protect the device from electrostatic discharge.
