TPS2075DB datasheet by Texas Instruments

TPS2075DB Frequently Asked Questions (FAQs)

• What is the maximum current that can be drawn from the TPS2075DB?
  The maximum current that can be drawn from the TPS2075DB is 1A per channel, but it's recommended to limit the current to 0.5A per channel for reliable operation.
• How do I ensure that the TPS2075DB switches on and off correctly?
  To ensure correct switching, make sure to connect the EN pin to a logic-level signal (e.g., 3.3V or 5V) and use a pull-down resistor (e.g., 10kΩ) to ground on the EN pin to prevent unwanted switching.
• What is the purpose of the OC pin on the TPS2075DB?
  The OC (Overcurrent) pin is an open-drain output that goes low when an overcurrent condition is detected on either channel. It can be used to alert the system to an overcurrent event or to trigger a shutdown sequence.
• Can I use the TPS2075DB to switch AC loads?
  No, the TPS2075DB is designed to switch DC loads only. It's not suitable for switching AC loads, as it's not designed to handle the high voltage and current transients associated with AC switching.
• How do I calculate the power dissipation of the TPS2075DB?
  To calculate the power dissipation, use the formula: Pd = (VIN - VOUT) x IOUT x Rds(on), where Rds(on) is the on-state resistance of the internal FETs, typically around 0.5Ω. Make sure to consider the thermal resistance and junction temperature to ensure reliable operation.
