LT1505 Constant-Current/Voltage High Efficiency Battery Charger DESCRIPTIO
The LT®1505 PWM battery charger controller fast charges multiple battery chemistries including lithium-ion (Li-Ion), nickel-metal-hydride (NiMH) and nickel-cadmium (NiCd) using constant-current or constant-voltage control.
Maximum current can be easily programmed by resistors or a DAC.
The constant-voltage output can be selected for 3 or 4 series Li-Ion cells with 0.
5% accuracy.
A third control loop limits the current drawn from the AC adapter during charging*.
This allows simultaneous operation of the equipment and fast battery charging without overloading the AC adapter.
The LT1505 can charge batte...
