TPS2158IDGN datasheet by Texas Instruments

TPS2158IDGN Frequently Asked Questions (FAQs)

• What is the maximum current that can be sunk by the TPS2158IDGN?
  The TPS2158IDGN can sink up to 100mA of current, making it suitable for applications that require a high current sink capability.
• How do I ensure that the TPS2158IDGN is properly powered on and off?
  To ensure proper power-on and power-off, the EN pin should be driven high to turn on the device, and driven low to turn it off. Additionally, the input voltage should be within the recommended operating range of 2.7V to 5.5V.
• What is the purpose of the FLT pin, and how do I use it?
  The FLT pin is an active-low fault indicator that signals when the device is in an overcurrent or undervoltage condition. It can be connected to a microcontroller or other logic circuit to alert the system of a fault condition.
• Can I use the TPS2158IDGN as a high-side switch?
  No, the TPS2158IDGN is a low-side switch, meaning it can only switch the ground connection of a load. It is not suitable for high-side switching applications.
• How do I calculate the power dissipation of the TPS2158IDGN?
  The power dissipation of the TPS2158IDGN can be calculated using the equation Pd = (VIN - VOUT) x IOUT, where VIN is the input voltage, VOUT is the output voltage, and IOUT is the output current.
