LT1510/LT1510-5  
Constant-Voltage/  
Constant-Current Battery Charger  
FEATURES  
■
plest, most efficient solution to fast-charge modern re-  
chargeablebatteriesincludinglithium-ion(Li-Ion), nickel-  
metal-hydride (NiMH)* and nickel-cadmium (NiCd)* that  
require constant-current and/or constant-voltage charg-  
ing. The internal switch is capable of delivering 1.5A DC  
current (2A peak current). The 0.1Ω onboard current  
sense resistor makes the charging current programming  
very simple. One resistor (or a programming current from  
a DAC) is required to set the full charging current (1.5A) to  
within 5% accuracy. The LT1510 with 0.5% reference  
voltageaccuracymeetsthecriticalconstant-voltagecharg-  
ing requirement for lithium cells.  
Charges NiCd, NiMH and Lithium-Ion Batteries ––

The LT1510 can charge batteries ranging from 2V to 20V.  
Groundsensingofcurrentisnotrequiredandthebattery’s  
negative terminal can be tied directly to ground. A saturat-  
ingswitchrunningat200kHz(500kHzforLT1510-5)gives  
high charging efficiency and small inductor size. A block-  
ing diode is not required between the chip and the battery  
becausethechipgoesintosleepmodeanddrainsonly3µA
