LTC1732EMS-8.4中文资料Lithium-Ion Linear Battery Charger Controller数据手册ADI规格书

描述 Description

DESCRIPTION
The LTC®1732-8.4 is a complete constant-current/constant-voltage linear charge 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% accuracy using external sense and program resistors. An internal resistor divider and precision reference set the final float voltage with ±1% accuracy.FEATURES
