LT1510 - Constant-Voltage/Constant-Current Battery Charger

With switching frequency as high as 500kHz, The LT1510 current mode PWM Battery Charger is the smallest, simplest, most efficient solution to fast-charge modern rechargeable batteries including lithium-ion (Li-Ion), nickel-metal-hydride (NiMH)* and nickel-cadmium (NiCd)* that require constant-current and/or constant-voltage charging. The internal Switch is capable of delivering 1.5A DC current (2A peak current). The 0.1 ohms 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 curren 587 t (1.5A) to within 5% accuracy. The LT1510 with 0.5% reference voltage accuracy meets the critical constant-voltage charging requirement for lithium cells. The LT1510 CAN charge batteries ranging from 2V to 20V. Ground sensing of current is not required and the batterys negative terminal CAN be tied directly to ground. A saturating Switch running at 200kHz (500kHz for LT1510-5) 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 3A when the wall adaptor is unplugged. Soft start and shutdown features are also provided. The LT1510 is available in a 16-pin fused lead power SO package with a thermal resistance of 50C/W, an 8-pin SO and a 16-pin PDIP.
