TPS2214ADB datasheet by Texas Instruments

TPS2214ADB Frequently Asked Questions (FAQs)

• What is the maximum current rating for each switch?
  The maximum current rating for each switch is 1.5A, but it's recommended to derate the current to 1A for reliable operation.
• How do I ensure proper power sequencing with the TPS2214ADB?
  To ensure proper power sequencing, connect the EN (enable) pin to a logic signal that turns on after the input voltage has reached a stable level. You can also use an external voltage supervisor or power-good signal to control the EN pin.
• What is the purpose of the EN (enable) pin, and how does it affect the switches?
  The EN pin is an active-high enable input that turns on or off all four switches simultaneously. When EN is low, all switches are turned off, and when EN is high, the switches are enabled and controlled by the individual switch control pins (S1-S4).
• Can I use the TPS2214ADB as a high-side switch?
  No, the TPS2214ADB is a low-side switch, meaning it can only switch the ground connection of a load. It's not suitable for high-side switching applications.
• How do I handle inrush current with the TPS2214ADB?
  To handle inrush current, you can add an external current-limiting resistor or inrush current limiter (ICL) in series with the switch output. You can also use a soft-start circuit or a controlled slew-rate power supply to reduce inrush current.
