The ADP3801 and ADP3802 are complete battery charging ICs. The devices combine a high accuracy final battery voltage control with a constant charge current control and an on-board Low Drop-Out Regulator (LDO). The accuracy of the final battery voltage control is guaranteed to 0.75% to safely charge Li-Ion batteries. An internal multiplexer allows the alternate charging of two separate battery stacks. The final voltage is pin programmable to one of three Li-Ion options: 4.2 V (one Li-Ion cell), 8.4 V (two Li-Ion cells), or 12.6 V (three Li-Ion cells). Paired with an external microcontroller for charge termination, the ADP3801/ADP3802 works as a fast charger for NiCad/ NiMH batteries or as a universal charger for all three battery chemistries. In addition, a pin is provided for changing the final battery voltage by up to 10% to adjust for variations in battery chemistry from different Li-Ion manufacturers without loss of accuracy in the final battery voltage.
