AIC1781 Datasheet Battery Charge Controller

Manufacturer: Analog Intergrations Corporation

Overview: AIC1781 Battery Charge Controller.

General 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.

The fast charge can also be cut off by maximum battery voltage and maximum battery temperature detection along with the safety timer to prevent charging under fault conditions of the charging system or the battery itself.

Key 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.
