ISL94203IRTZ-T7A application field and working principle
ISL94203IRTZ-T7A is an advanced battery-management device that provides a single-cell battery charger and protection circuitries. Specifically designed for high-performance ultra-low standby power system, this device is a current-mode step down regulator adopting adaptive on-time control, designed to provide compact size and fast transient response. The integrated battery charger improves charging time, which is essential for portable applications.
In addition, the ISL94203IRTZ-T7A battery-management device provides protection for both over-voltage and under-voltage conditions. As a safety precaution, over-charge, over-discharge, and over-temperature events are monitored and suitable protection measures are taken to ensure safe operation.
Application Fields
The ISL94203IRTZ-T7A is ideal for use in applications such as laptops, tablet PCs and portable media players, where a dependable power source is expected in a small form factor.
Work Principle
The ISL94203IRTZ-T7A operates on an Active Voltage Positioning principle. During normal battery charging, the Active Voltage Positioning maintains the battery voltage at the target voltage by actively controlling the charging current. When the battery voltage reaches the set target voltage, the charger automatically reduces the amount of current output to maintain the desired voltage. When the target voltage drops due to a decrease in the internal resistance of the battery, the charger automatically increases the amount of current necessary to maintain the desired voltage.
Also, the ISL94203IRTZ-T7A guarantees safe operation of the circuit by providing protection against overcharging, undercharging, overtemperature and over-discharge conditions. To provide over-charge protection, the device can detect when the voltage and temperature of the battery exceeds a certain level and shut down the charging procedure automatically.
The device also offers an over-discharge protection feature. This feature allows the device to detect when the voltage of the battery drops below a certain level and shut down the charging operation. This feature is important since battery damage can occur after too many deep discharging cycles.
ISL94203IRTZ-T7A also provides over-temperature protection. This feature helps to reduce the risk of thermal runaway in batteries by detecting when the battery temperature reaches a certain level and automatically shut down the charging operation.
Conclusion
The ISL94203IRTZ-T7A is an advanced battery-management device that providing reliable charging and protection for high-performance portable applications. This device operates on an Active Voltage Positioning principle, providing over-charge, over-discharge and over-temperature protection. The device is ideal for applications such as laptops, tablet PCs and portable media players, where a dependable power source is required in a small form factor.
