The KIT34673EPEVBE is an evaluation module for MC34673, a cost effective fully integrated battery charger for Li-Ion or Li-polymer batteries. It tolerates an input voltage up to 28V, which eliminates the input over voltage protection circuit required in handheld devices. A charge cycle includes trickle, constant current and constant voltage charge modes. The constant current mode current is programmable up to 1.2A with an external resistor. The constant voltage is fixed at 4.2V. The trickle mode current is preset to 20% of the constant current mode current when the battery voltage is lower than the trickle mode threshold. The end of charge current threshold is preset to 10% of the constant current mode current to save the board space and cost. A charge current thermal foldback limits the charge current when the IC internal temperature rises to a preset threshold. The MC34673 has a 2.6V falling power on reset threshold making it perfect to work with current limited power supplies.
