description

The LTC ® 4060 is a complete NiMH or NiCd battery fast charging system. Only a small number of external components are required to design a stand-alone linear charging system.

The external PNP transistor provides the charging current and is a user-programmable resistor. A small external capacitor sets the maximum charging time. is necessary without the need for external current-sense resistors and isolation diodes.

The integrated circuit automatically senses the DC input power and battery insertion or removal. Originally controlled at C/5 for re-discharge of the battery, fast charging before application. Using the -ΔV detection method, fast charge termination. The backup termination is provided by a programmable timer and battery overvoltage detector. An optional external NTC thermistor is available for temperature-based charging qualifications. An optional programmable charging function that automatically charges and then discharges the battery.

Complete manual shutdown with the SHDN pin, while eliminating the LTC4060 that the input power will automatically go into sleep mode. 在关机或睡眠模式，电池消耗

LTC4060 is - two flat (0.75mm) 16-pin 5mm x 3mm DFN and 16-lead TSSOP packages. These two types of metal mold loading pads expose optimal heat dissipation properties.
