The LT1510CS#PBF is a constant-voltage/constant-current Battery Charger with switching frequency as high as 500kHz. This current mode PWM battery charger is the smallest, simplest, most efficient solution to fast-charge modern rechargeable batteries. The 0.1ohms onboard current sense resistor makes the charging current programming very simple. The LT1510 with 0.5% reference voltage accuracy meets the critical constant-voltage charging requirement for lithium cells. It can charge batteries ranging from 2 to 20V. Ground sensing of current is not required and the battery's negative terminal can be tied directly to ground. A saturating switch running at 200kHz gives high charging efficiency and small inductor size. A blocking diode is not required between the chip and the battery because the chip goes into sleep mode and drains only 3μA when the wall adaptor is unplugged. Soft-start and shutdown features are also provided.

• Charges nickel-cadmium (NiCd), nickel-metal-hydride (NiMH) and Lithium-ion (Li-ion) batteries
• Only one 1/10W resistor is needed to program charging current
• High efficiency current mode PWM with 1.5A internal switch and sense resistor
• 3% Typical charging current accuracy
• Precision 0.5% voltage reference for voltage mode charging or overvoltage protection
• Current sensing can be at either terminal of the battery
• Low reverse battery drain current (3μA)
• Charging current soft-start
• Shutdown control
