Diodes Incorporated — Analog and discrete power solutions

Charger

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
