U-504 Using the bq2000/T to Control Fast Charge (Rev. B)
PDF, 193 Kb, 修订版: B, 档案已发布: Dec 2, 2004
The bq2000/T are programmable, monolithic ICs for fast-charge management of nickel cadmium, nickel metal-hydride, and lithium-ion batteries in single- or multichemistry applications. This application note discusses simple ways to select all necessary components to implement various switch-mode topologies. It also discusses how to configure the bq2000/T inputs to accomodate different appplication c
