Connect 5V on VIN.
Connect 3.7V on VBAT.
Connect 500mA electronic load on VBAT.
Verify that no shunts across all jumpers.
Turn on Power Supplies and electronic load.
Green LED should be on, indicating normal
charging operation.
If current meter is in series with VIN, it shall read
250mA as the charging current.

JP1 - Selects the VIN pin to be connected to either a wall
adapter, or to a USB connector. If the J1 connector is being
used, a shunt must be installed across ‘WALL CUBE TO
VIN’, or if the J3 (USB) connector is being used, a shunt
must be installed across ‘USB TO VIN’. J1, J3 and JP1 can
be ignored if the power supply is connected directly to the
VIN test point, which is directly connected to the VIN pin of
the IC. A current meter, to measure the input current, can
replace the shunt mentioned above.
JP2 - Can connect the VBAT pin to the battery. If the J2
connector is being used, a shunt must be installed across
JP2. In this case, a current meter can also replace the shunt
to measure the VBAT current.
JP3 - Can connect the TEMP pin to the battery. Usually no
shunt is needed for JP3, as the Eval board can simulate

A 9-bit DIP switch is provided to set up voltage, current

functionality of the bits are described in Table 1.

an attached thermistor is applied on J2 does it become
necessary to install a shunt across JP3, simultaneously
turning off bits 7, 8, and 9 on the DIP switch.
JP4 - Selects USB modes; a shunt across IREF and V2P8
will set USB 255mA mode, a shunt across IREF and GND
will set USB 100mA mode. When the charge current is
programmed by the resistors connected to IREF pin, no
shunt should be installed on JP4.
