2.2 Equipment Setup

Use the following list to set up the EVM testing equipment:

  1. Review EVM connections in Table 1-2.
  2. Set PS1 for 5-V DC, 2-A current limit and then turn off the supply.
  3. Connect the output of PS1 in series with a current meter to J1 (VBUS and PGND).
  4. Connect a voltage meter across TP12 (VBUS) and TP31 (PGND), or across J1.
  5. Turn on Load #1, set to constant voltage mode, and output to 2.5-V. Disable Load. Connect Load in series with a current meter (multimeter), ground side, to J4 (BAT and PGND) as shown in Figure 2-1.
  6. Connect one voltage meter across TP16 (BAT) and TP30 (PGND), or across J4-3 and J4-1 as shown in Figure 2-1.
  7. Connect one voltage meter across TP17 (SYS) and TP30 (PGND), or across J2-1 and J2-2 as shown in Figure 2-1.
  8. Connect one voltage meter across TP14 (VPB) and TP32 (PGND), or across J3-1 and J3-2 as shown in Figure 2-1.
  9. Connect the EV2300/2400 USB interface board to the computer with a USB cable and from I2C port to J5 with the 4-pin cable. The connections are shown in Figure 2-1.
  10. Install shunts as shown in Table 1-3.
