TPS22913: What is RL in the datasheet?

Part Number: TPS22913

The datasheet for this part refers to RL in the electrical characteristics and many of the application curves, however there is no concrete explanation of RL.  Is it an external part as the diagram on page 1 implies? although the electrical characteristics table refers to RL = 1Mohm when the chip is OFF, and 10ohms when the chip is ON. 

Thanks

  • Hi Caitlin,

    RL is an external load resistance added to VOUT to simulate the current draw from a system load. The device can handle any load from 0A to 2A, but 10Ω is TI's load switch standard for timing and switching characteristics. RL is not an internal device spec.

    Thanks,
