The LTC
®
4060 is a complete fast charging system for NiMH
or NiCd batteries. Just a few external components are
needed to design a standalone linear charging system.
An external PNP transistor provides charge current that is
user programmable with a resistor. A small external capaci-
tor sets the maximum charge time. No external current
sense resistor is needed, and no blocking diode is required.
The IC automatically senses the DC input supply and bat-
tery insertion or removal. Heavily discharged batteries are
initially charged at a C/5 rate before a fast charge is applied.
Fast charge is terminated using the –∆V detection method.
Backup termination consists of a programmable timer and
battery overvoltage detector. An optional external NTC ther-
mistor can be used for temperature-based qualification of
charging. An optional programmable recharge feature au-
tomatically recharges batteries after discharge.
Manual shutdown is accomplished with the SHDN pin, while
removing input power automatically puts the LTC4060 into
sleep mode. During shutdown or sleep mode, battery drain
is <1µA.
The LTC4060 is available in both low profile (0.75mm) 16-
pin 5mm
×
3mm DFN and 16-lead TSSOP packages. Both
feature exposed metal die mount pads for optimum ther-
mal performance.
