AIC1781 - Battery Charge Controller

Description

The AIC1781 fast charge controller IC is designed for intelligent charging of NiMH or NiCd batteries without the risk of overcharge.

∆V detection (-0.25%), 0 ∆V detection (peak voltage timer) and ∆T / ∆t detection are the primary methods employed by the AIC1781 to terminate fast charge.

Features

  • Fast Charge Control of NiMH/NiCd Batteries, even with a Fluctuating Charging Current. Fast Charge Termination by: ∆T / ∆t ,.
  • ∆V , 0 ∆V , Safety Timer, Maximum Temperature, Maximum Voltage. Linearly Adjustable ∆T / ∆t Detection Slope and Safety Timer. Adjustable Peak Voltage Timer for 0 ∆V . Battery Voltage Protection Range Selectable. Selectable Battery Temperature Protection Mode. Protection against Battery Voltage and Battery Temperature Faults. Selectable LED Display Mode for Battery.
