Layout considerations
Place decoupling capacitors C1 and C2 as close as possible to the VIN pin and BAT pin
respectively.
Place the charge current setting resistor as close as possible to the ISET pin to minimize
the parasitic capacitance between the ISET pin and ground.
Use wide traces to connect input power to the VIN pin and BAT pin to the battery.
To get better thermal performance, put the EPAD pin of the MC34673 on a large ground
plane on the component side and use a via array to connect the EPAD pin to the ground
layer, or the large ground plane in the other layer.
Evaluation Board Configuration
Pin Headers
The JP1 pin header links the external DC power supply to the VIN pin of the MC34673. This
allows the user to measure the current from the DC power supply to the evaluation board when
using a current meter between pin1 and pin2 of JP1. The default setting of JP1 is to short pins 1
and 2.
The JP2 pin header selects the voltage to supply the D1 and D2 LED indicators. Shorting pins 1
and 2 selects VIN to power the LEDs. Shorting pins 2 and 3 selects the BAT pin to power the
LEDs.
