LINEAR LT1510/LT1510-5 handbook
Update: 29 September, 2023
LT1510/LT1510-5 is a simple and efficient solution for fast-charging 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. It features an internal switch capable of delivering 1.5A DC current (2A peak current). The charging current programming is simplified with a 0.1Ω onboard current sense resistor, requiring only one resistor or a programming current from a DAC to set the full charging current (1.5A) within 5% accuracy. With 0.5% reference voltage accuracy, the LT1510 meets the critical constant-voltage charging requirement for lithium cells. It can charge batteries ranging from 2V to 20V, and does not require ground sensing of current, allowing the battery's negative terminal to be tied directly to ground. The chip operates with a saturating switch running at 200kHz (500kHz for LT1510-5), providing high charging efficiency and small inductor size. A blocking diode is not needed between the chip and the battery as the chip goes into sleep mode and drains only 3µA when the wall adaptor is unplugged. Soft start and shutdown features are also included.
