Figure 2-1 Equipment Test Setup

Use the following list to set up the EVM testing equipment. Refer to Figure 3-1 for the test setup connections to the EVM.

  1. Review the EVM connections in Table 3-1.
  2. Install jumpers as shown in Table 3-2.
  3. Set PS1 for 8.3 VDC, 1 A current limit, and then turn off the supply.
  4. Connect PS1 to J1 (VIN1 and GND).
  5. Connect a voltage meter across TP1 (VAC1) and TP37 (GND) to measure the input voltage as seen from the VAC1 bump of the U1 charger.
  6. Connect a voltage meter across TP2 (VBUS_M) and TP37 (GND) to measure the input voltage as seen from the VBUS bumps of the U1 charger.
  7. Set Load #1 to constant voltage mode with an output of 4.0 V, and then disable the load.
  8. Connect Load #1 to J2 (VOUT and PACK-). Connect a current meter in series to measure the output current, as shown in Figure 3-1.
  9. Connect a voltage meter across TP5 (VOUT_M) and TP37 (GND) to measure the output voltage as seen from the VOUT bumps of the charger.
