Test Setup with the Evaluation Board
7.2
There are 10 connecting pads (J1 to J10 with corresponding names) on the evaluation board to
let the user simply connect the board to their system. The GND pads link power ground of the
MC34671. The INPUT pad connects an external DC power supply to the evaluation board. The
PPR, CHG, EN, FAST, and ISET pads link to the corresponding pins of the MC34671. The VL
pad is used for the user to supply a logic I/O voltage to the evaluation board, in case the
application system needs a logic voltage level to interface to the PPR, CHG, and FAST pins of
the MC34671. The VBAT pad connects the positive pole of the Li+ battery being charged.
7.3
The KIT34671 evaluation board provides 7 signal test points and 3 ground test points for users
to conveniently hookup multi-meters and oscilloscope probes to evaluate the MC34671. The test
points connect the pins of the MC34671 with the same name directly.

The test setup is shown in
limit to the INPUT pad on the evaluation board. Connect the positive and negative polarities of
the Li+ battery to the VBAT pad and the GND pad on the evaluation board respectively. Use a
current meter and a voltage meter to measure the charge current and the voltage respectively.
Turn on the power supply and the evaluation board starts charging the battery.
