LTC4060

Standalone Linear NiMH/NiCd

Fast Battery Charger

FEATURES

DESCRIPTIO

TheLTC^®4060isacompletefastchargingsystemforNiMH

or NiCd batteries. Just a few external components are

needed to design a standalone linear charging system.

■

Complete Fast Charger Controller for Single,

2-, 3- or 4-Series Cell NiMH/NiCd Batteries

■

No Firmware or Microcontroller Required

■

Termination by –∆V, Maximum Voltage or

An external PNP transistor provides charge current that is

userprogrammablewitharesistor.Asmallexternalcapaci-

tor sets the maximum charge time. No external current

senseresistorisneeded,andnoblockingdiodeisrequired.

■

No Sense Resistor or Blocking Diode Required

■

Automatic Recharge Keeps Batteries Charged

■

Programmable Fast Charge Current: 0.4A to 2A

■

The IC automatically senses the DC input supply and bat-

tery insertion or removal. Heavily discharged batteries are
