Torex Semiconductor Co., Ltd. has developed the XC6810 series of multifunctional ultra-compact charging ICs suitable for supporting wireless power transfer lithium-ion batteries. The XC6810 series are ultra-compact charging ICs for Li-ion batteries, suitable for small wearables, hearables, and IoT devices. It has various functions such as charge and discharge control, wireless power supply support, etc.
The charging current is 1mA~25mA, suitable for small lithium-ion batteries, and can provide a wide range of charging voltage from 3.8V to 4.4V. This product is equipped with a shutdown function that inhibits battery discharge when stored or not in use, and a wake-up function using an external button. It effectively extends the life of the battery and battery equipment. The CSO pin that displays the charging status can be used in addition to the traditional driver In addition to the charging status display by the LED, there are also models that display the charging level by the frequency of use, and use a microcomputer for charging monitoring. In addition, the product is also equipped with a battery voltage monitoring function and a battery low voltage notification function, which can monitor the battery voltage through a microcomputer.
The input voltage is 3.5V~28V, and it supports energy harvesting charging methods such as wireless charging or solar energy. For the contact charging method using the base, etc., select a model that uses a 2-wire communication method that uses the CSO pin to modulate the input current to know the charging status, and you can display the charging status and control the charging through the base.
