TDA7439 IC Audio Processor IC

Product Overview

The FM05PF, manufactured by Fine Made Microelectronics Group Co., Ltd., is a professional 5-cell rechargeable battery protection IC designed for high-demand applications like electric tools, electric bicycles, and UPS systems. It provides comprehensive monitoring of cell voltage, charge/discharge current, and ambient temperature.

Key Features

• High-Precision Voltage Monitoring: Ensures the safety of each individual battery cell within the 5-cell series stack.

• Adjustable Delay Times: Protection delay times for overcharge, over-discharge, and overcurrent conditions can be customized by adjusting the value of external capacitors.

• Comprehensive Protection: Monitors cell voltage, charge/discharge current, and ambient temperature to trigger safety shutdowns during overcurrent, short-circuit, or overcharge/discharge events.

• High Integration: Combines complex monitoring logic into a single device to reduce component count in battery management systems.

• Selectable Cell Count: Features a SET terminal allowing for configuration between 4-cell and 5-cell applications.

• Temperature Management: Includes an NTC thermistor interface and an adjustable high-temperature protection threshold via an external resistor.
