IMPORTANT: DO NOT APPLY HIGHER THAN A 12V DC INPUT VOLTAGE TO VIN IF THE
PINS 1 and 2 ARE SHORTED.
The absolute maximum voltage at the PPR and CHG pin is 12V. When applying higher than a
12V input voltage, select the BAT pin to power the LEDs.
The JP3 pin header allows the user to disable the MC34673 when shorting pins 1 and 2. Leaving
it open enables the MC34673.
The JP4 pin header links the BAT pin and the external battery connector. It allows the user to
measure the charging current from the MC34673 into the battery with a current meter between
pins 1 and 2. The default setting is to short pins 1 and 2.
JP5 and JP6 are used to let the user supply an I/O logic voltage to PPR and CHG, so the system
can interface to the PPR and CHG signals with the same voltage level. When using LEDs to
indicate the charging status, leave JP5 and JP6 open. When interfacing the PPR and CHG signal
to the system, short pins 1 and 2 of JP5 and JP6, and leave JP2 open.
JP7 and JP8 set the charge current. The current values related to JP7 and JP8 settings are
shown in
JP9 selects the power supply for pulling up the voltage of the FAST signal. Shorting pins 1 and
2 selects the externally supplied I/O logic voltage. Shorting pins 2 and 3 selects the battery
voltage.
The default configuration of the evaluation board is a standalone charger. The default settings of
the evaluation board are shown in
When using the evaluation board to connect to the system, apply the required I/O logic voltage
at the VL pad of the evaluation board and set the pin header jumpers as shown in
