FEATURES  
DESCRIPTIO  
■
Complete NiMH/NiCd Charger for 1 to 16 Cells  
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.  
■
No Microcontroller or Firmware Required  
■
550kHz PWM Current Source Controller  
■
No Audible Noise with Ceramic Capacitors  
■
Wide Input Voltage Range: 5.5V to 34V  
■
Programmable Charge Current: 5% Accuracy  
The LTC4010 automatically senses the presence of a DC  
adapter and battery insertion or removal. When an exter-  
nal DC source is not present, the LTC4010 enters shut-  
down and supply current drawn from an installed battery  
drops to the lowest possible level. Heavily discharged  
batteriesareprechargedwithatricklecurrent.TheLTC4010  
can simultaneously use both –∆V and ∆T/∆t fast charge  
termination 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.

APPLICATIO S  
All LTC4010 charging operations are qualified by actual  
charge time and maximum average cell voltage. Charging  
may also be gated by minimum and maximum tempera-  
ture limits. NiMH or NiCd fast charge termination param-  
eters are pin selectable.
