EQUIPMENT REQUIREMENT
Evaluation requires the following equipments:
1. DC power source. The output voltage should exceed 6.0V, and output current greater than 3A.
2. Battery simulator or a single-cell battery pack. The battery simulator’s output rating should
exceed 4.5V/7.0A. When using a real battery pack, please observe all precautions on the
battery manufacturer’s data sheet first and ensure the charger’s setting doesn’t exceed the
battery’s absolute maximum specifications.
3. Oscilloscope. A single voltage probe and a single current probe.
4. Multi-meter.
Charge Function
1 Connect the jumper “VCC”.
2 The jumpers “DCP”, “SDP1” and “SDP2” are used for the input DP1/DM1 detection setting.
Connect “DCP” and leave “SDP1” and ”SDP2” float as default, the DP1/DM1 detection will be
set as DCP, the I
INLIMIT
is set through R
ILIM
.
Otherwise, only connect “SDP1” and “SDP2”, or leave the 3 jumpers float will set the I
INLIMIT
=
500mA.
3 Attach the positive and negative ends of the battery to the “BATT” and “GND” terminals,
respectively. If it’s a battery simulator, please preset the voltage to 3.8V (typical value) first.
4 Preset the DC power source to 5.0V. Then attach the DC output port and ground to the “VIN”
and “GND” terminals, respectively.
5 Turn on the DC power source. The charger will start. Use the oscilloscope to verify that the 3A
charge current is being delivered to the battery.
