LTC4002 Standalone Li-Ion Switch Mode Battery Charger FEATURES DESCRIPTIO Wide Input Supply Range: The LTC 4002 is a complete battery charger controller for 4.7V to 22V 4.2 Version one (4.2V) or two (8.4V) cell lithium-ion batteries. With a 8.9V to 22V 8.4 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 4.2V per cell with 1% accuracy. Constant Switching Frequency for Minimum Noise When the input supply is removed, the LTC4002 automati- 5% Charge Current Accuracy cally enters a low current sleep mode, dropping the battery Low 10A Reverse Battery Drain Current drain current to 10A. An internal comparator detects the Automatic Battery Recharge near end-of-charge condition while an internal timer sets Automatic Shutdown When Input Supply is Removed the total charge time and terminates the charge cycle. After Automatic Trickle Charging of Low Voltage Batteries the charge cycle ends, if the battery voltage drops below Battery Temperature Sensing and Charge 4.05V per cell, a new charge cycle will automatically begin.
