- U-504 Using the bq2000/T to Control Fast Charge (Rev. B)PDF, 193 Kb, Revisión: B, Archivo publicado: dic 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 - Battery Charger Termination Issues With System Load Applied Across Battery (Rev.
