Linear Technology LTC1325 Battery Management System Application Note 64
The document introduces the LTC1325, a flexible battery management integrated circuit designed to charge various battery types including Nickel-Cadmium, Nickel-Metal Hydride, Sealed Lead-Acid, and Lithium-Ion. It details how an external microprocessor controls the chip's functional blocks via a serial interface to implement custom charging algorithms.
The note outlines basic techniques for multi-stage charging (Fast Charge, Top-Off, Trickle) and explains how the LTC1325 handles fault protection through monitoring of battery temperature, cell voltage, and elapsed time. It also covers the chip's capacity monitoring features known as 'Gas Gauge' mode.
