NXP KIT34671EPEVBE 评估套件, 用于MC34671锂电池充电器
The is an evaluation module for MC34671, 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 CC and constant voltage CV charge modes. The constant current is programmable up to 600mA, with an external resistor. The constant voltage is fixed at 4.2V. The trickle charge current is preset to 20% of the CC current when the battery voltage is lower than the trickle charge threshold. The end of charge current threshold is preset to 10% of the CC current to save board space and cost. A charge current thermal foldback feature limits the charge current when the IC internal temperature rises to a preset threshold. The MC34671 has a 2.6V falling power on reset POR threshold, making it perfect to work with current limited power supplies.
