LTC4002. Standalone Li-Ion Switch Mode Battery Charger U. FEATURES DESCRIPTIO. Wide Input Supply Range: The LTC 4002 is a complete battery charger controller for to 22V Version one ( ) or two ( ) cell lithium-ion batteries. With a to 22V Version 500kHz switching frequency, the LTC4002 provides a High Efficiency Current Mode PWM Controller with small, simple and efficient solution to fast charge Li-Ion 500kHz Switching Frequency batteries from a wide range of supply voltages. An external 1% Charge Voltage Accuracy sense resistor sets the charge current with 5% accuracy. End-of-Charge Current Detection Output An internal resistor divider and precision reference set the 3 Hour Charge Termination Timer final float voltage to per cell with 1% accuracy.
LTC4002 3 4002f ELECTRICAL CHARACTERISTICS (LTC4002-4.2) The denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VCC = 10V unless otherwise noted. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS
