LTC4010  
High Efficiency Standalone  
Nickel Battery Charger  
FeaTures  
DescripTion  
The LTC®4010 provides a complete, cost-effective nickel  
battery fast charge solution in a small package using few  
external components. A 550kHz PWM current source  
controller and all necessary charge initiation, monitoring  
and termination control circuitry are included.  
n
Complete NiMH/NiCd Charger for 1 to 16 Cells  
n
No Microcontroller or Firmware Required  
n
550kHz PWM Current Source Controller  
n
No Audible Noise with Ceramic Capacitors  
n
Wide Input Voltage Range: 5.5V to 34V  
n
Programmable Charge Current: 5% Accuracy  
The LTC4010 automatically senses the presence of a DC  
adapterandbatteryinsertionorremoval.Whenanexternal  
DC source is not present, the LTC4010 enters shutdown  
and supply current drawn from an installed battery drops  
to the lowest possible level. Heavily discharged batteries  
are precharged with a trickle current. The LTC4010 can  
simultaneously use both –∆V and ∆T/∆t fast charge ter-  
mination techniques and can detect various battery faults.  
If necessary, a top-off charge is automatically applied to  
NiMH batteries after fast charging is completed. The IC  
will also resume charging if the battery self-discharges  
after a full charge cycle.
