2.4.3 Test Instructions

For this EVM to operate properly, the following components must be connected and properly configured.

  1. Set input power supply to 6 V with current limit greater than 400 mA. Set battery simulator to 4.8V with compliance to support 400 mA. Turn off supply and battery simulator.
  2. Connect input voltages to J1 and battery simulator to J2 on the EVM.
  3. Configure all EVM jumpers to factory setting, refer to table below.
  4. Disconnect JP6 Jumper, this disconnects C7 & C8.
    1. This test set up uses external load, disconnect on board super capacitors.
  5. Turn on battery simulator.
  6. Turn on input power supply.
    1. OUT voltage must be 4.8V and charge current 400 mA.
    2. PG LED D1 is ON.
    3. STAT LED D2 is OFF.
  7. Raise input power supply to 20 V.
    1. Charging stops and STAT pin flashes at 1 Hz.
    2. PG LED D1 is OFF.
    3. Lower input voltage to 6 V to clear fault.
  8. Simulate charge complete by increasing battery simulator voltage to 5 V.
    1. Current tapers to 0 mA.
    2. STAT LED D2 switches to ON.
