High Input Voltage Travel Charger for Single-cell Li-Ion Batteries
The MC34674 is a fully integrated single-cell Li-Ion and Li-Polymer battery charger optimized for travel charger applications. The few external components required include a dual-color LED for chargestatus indication, a negative temperature coefficient (NTC) thermistor circuit for setting the charge temperature window, and two decoupling capacitors. The high input voltage, up to 28V, allows low-cost ac/dc converters to be used for further system cost reduction. A typical charge cycle of the MC34674 includes trickle, constant-current (CC) and constant-voltage (CV) charge modes. The CC-mode current is selectable from 50mA to 1.05A with 8% accuracy and the constantoutput voltage in the CV-mode is fixed at 4.2V with 0.4% accuracy over -20°C to 70°C temperature range. The MC34674 has all the features such as trickle charging for a deeply
