With the continuous improvement of the performance of smart mobile devices, batteries are becoming more and more overwhelmed, and mobile power products have grown stronger. In addition, the increase in user demand also requires products to move toward flexible design. At present, the lithium battery charge management ICs on the market are mostly 1A linear charging. The shortcomings are: 1A linear charging temperature is high, and on-chip thermal resistance loss is serious, which makes the current of the linear battery charging management IC difficult to achieve 2A, even through The external expansion MOS is 2A, the temperature is relatively high, and the conversion efficiency is about 70%. Therefore, switching charging is very necessary. At present, the demand for lithium battery charging management ICs on the market is mainly: 2A~3A high current integrated MOS, switching efficiency up to 90%, and low temperature charging management IC. In addition, multi-functional integrated chips are becoming more and more popular, including switching charge management, battery power detection display, synchronous boost output current limiting and other functions integrated on a single chip to become the current trend.
Integrated and versatile, cost-effective and reliable
The "three in one" and "five in one" chips are welcomed by the market. The ZS6366 is a portable power management IC that integrates the switching lithium battery charge management, synchronous boost output current limit, battery power detection display, LED flashlight and button control. It is charged in the switching mode, and integrates the charging method including trickle charging, constant current charging and constant voltage charging. The floating charging voltage accuracy can reach ±1% in the full temperature range, and the charging current temperature is low, and the charging efficiency is low. Higher advantages, with appropriate peripheral devices can achieve a charging current of 2A or higher.
In the charging state, if the output USB is connected to the load at the same time, the dynamic path adjustment function of the ZS6366 will intelligently distribute the input current to the load first. If the load current increases, the charging will be automatically turned off, and the charging current will gradually decrease to a certain value. Turn on the battery when the value is turned on, effectively limiting the input current and preventing damage to the powered adapter or USB. At the same time, you can also switch charging or discharging by pressing the button.
The ZS6366's DC-DC boost achieves ±1% accuracy, provides up to 90% boost conversion efficiency, and features accurate boost current limiting. ZS6366 is equipped with 4 LED constant current drive ports to intelligently display battery power. The chip has built-in logic lock function to prevent the status of power indication from being unstable. At the same time, it integrates battery real voltage tracking technology to track the actual internal power of the battery and prevent charging and discharging. Voltage deviation. In addition, the ZS6366 has multiple protection designs, including load overcurrent protection, short circuit protection, soft start protection, etc. At the same time, the chip port is designed with high performance ESD protection circuit, which makes the chip extremely reliable. The battery is turned off at 2.9V, effectively protecting and extending the battery charge and discharge times and life.
According to the working frequency response ranges, speakers can be classified into tweeters, mid ranges, woofers and full ranges.
