The integrated circuit ISL6295CVZ is a Battery Management IC (BMC) specifically designed to provide management, monitoring and protection functions to a cell Li-ion Polymer battery with a variety of configuration options. ISL6295CVZ\'s discharge and charge logic work together to ensure that the battery is always within appropriate operating parameters.

Application Field

The ISL6295CVZ is used in many applications such as mobile phones, tablets, tablets, notebook PCs, ultra-books, e-bike and other portable devices. Due to its low profile and small size, the ISL6295CVZ is an ideal solution for these applications. The ISL6295CVZ offers many features, such as:

• Accurate current and voltage monitoring, especially during rapid and high-rate charging and discharging.
• Full protection for both over-voltage and over-current events.
• Temperature protection.
• Multiple charging modes, such as constant-current/constant-voltage charging.
• Charge termination and over-discharge protection with programmable thresholds.
• Detects battery-full condition to ensure efficient and safe charging.

Working Principle

The ISL6295CVZ works by sensing and monitoring the voltage, current and temperature of the battery, as well as the external voltage and current. It then uses this information to detect any abnormalities and provide safety protection to the battery, as well as to regulate the charging and discharging process.

The ISL6295CVZ has three main input pins: VSENSE, CSENSE and TEMP. The VSENSE pin is used to monitor the battery voltage, whereas the CSENSE pin is used to monitor the battery current. The TEMP pin is connected to an external temperature sensor to allow the IC to monitor the temperature.

The ISL6295CVZ also has two control pins: CHG and DISCHG. These two pins allow the user to configure the charging and discharging modes of the battery. The CHG pin is used to control the charging process and the DISCHG pin is used to control the discharging process.

The ISL6295CVZ also has two output pins: OT and OV. The OT pin goes low when the battery is exceeding the temperature threshold, indicating an over-temperature condition. The OV pin goes low when the cell voltage is exceeding the overvoltage threshold, indicating an over-voltage condition.

Finally, the ISL6295CVZ has two programmable pins: EN_VREF and FLAG. The EN_VREF pin is used to enable or disable the voltage reference of the IC, which determines the operating range of the ISL6295CVZ. The FLAG pin is used to indicate the full charge condition of the battery.

To summarize, the ISL6295CVZ is a Battery Management IC designed for Li-ion Polymer batteries. It provides accurate current and voltage monitoring, temperature protection, multiple charging modes, and charge termination and over-discharge protection. It also provides protection against over-voltage and over-current events, as well as indicating when the battery is full.
