Our portfolio of charger controllers provide fast, reliable charge termination in both NiCd and NiMH battery applications, power tools, and consumer electronics. We also offer fully integrated single-cell Li-ion battery charger ICs, which operate in a constant-current/constant-voltage (CC/CV) charging profile, without employing external FETs or blocking diodes. These devices feature:

• Five charging states for different battery conditions
• Excellent battery protection and full-charge detection schemes
• Fuel-gauge counter that accounts for battery self-discharge compensation
• Key delay functionality to reject multiple inputs at Tact switch (about 0.125s ignorance)
• Internal voltage regulator
• Integrated DC/DC step-down controller
