8.2.1 Design Requirements

For this design example, use the following input parameters:

  1. The TPS2001EDBV operates from a 5-V to ±0.5-V input rail.
  2. What is the normal operation current, for example, the maximum allowable current drawn by portable equipment for BC1.2 is 1500 mA, so the normal operation current is 1500 mA, and the minimum current limit of power switch must exceed 1500 mA to avoid false trigger during normal operation. For the TPS2001E device, target 2-A continuous output current application.
  3. What is the maximum allowable current provided by up-stream power, the maximum current limit of power switch that must lower it to ensure power switch can protect the up-stream power when overload is encountered at the output of power switch. For the TPS2001E device, the maximum IOS is 3.5 A.
