LT1571EGN-2 - Brand New Analog Devices Battery Management ICs
-
DESCRIPTION
The LT ®1571 PWM battery charger is a simple, efficient solution to fast- charge rechargeable batteries including lithium-ion (Li-Ion), nickel-metal- hydride (NiMH) and nickel-cadmium (NiCd) using constant-current and/or constant-voltage control. The internal switch is capable of delivering 1.5A DC current (2A peak current). The onboard current sense resistor (0.1Ω) allows simple charge current programming to within 5% accuracy using a low cost external resistor. The constant-voltage output can be selected for 4.1V or 4.2V per cell with 0.6% accuracy.
