LTC1732EMS-4 - Brand New Analog Devices / Linear Technology Battery Management ICs
-
DESCRIPTION
The LTC®1732 is a complete constant-current/constant-voltage linear charger controller for lithium-ion (Li-Ion) batteries. Nickel-cadmium (NiCd) and nickel metal-hydride (NiMH) batteries can also be charged with constant current using external termination. Charge current can be programmed with 7% (max) accuracy using external sense and program resistors. An internal resistor divider and precision reference set the final float voltage with 1% accuracy. The SEL pin allows users to charge either 4.1V or 4.2V cells.
