Product Summary
The LT1510-5CGN is a current mode PWM battery charger.The LT1510-5CGN is the smallest, simplest, most efficient solution to fast-charge modern rechargeable batteries including lithium-ion (Li-Ion), nickelmetal- hydride (NiMH)* and nickel-cadmium (NiCd) that require constant-current and/or constant-voltage charging. The LT1510-5CGN is capable of delivering 1.5A DC current (2A peak current). The 0.1W 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 LT1510-5CGN with 0.5% reference voltage accuracy meets the critical constant-voltage charging requirement for lithium cells.
