Equipment

2.1.1 Power Supplies
Power Supply 1 (PS#1) is a power supply capable of supplying 5 V at 2 A.
Optional Power Supply 2 is for use with optional battery simulated load (PS#2), a power supply capable of
supplying 5 V at 2 A.
2.1.2 Battery Pack or Simulated Load
A Li-ion, single-cell pack with capacity of at least 1200 mAh can be used or a simulated load of 2.8 Ω (two
5.6-Ω, ≥ 10-W power resistors in parallel), with a 0.1-Ω current sense in the return to the UUT and a power
silicon diode (cathode) connected to the BAT+ side of the load.
