A few days ago, Texas Instruments (TI) launched a high-integrated battery management solution that reached the lowest static current (IQ) in the industry. This is only 700NA with a buck converter solution at the operating voltage of 1.8V. The battery life can be extended to minimize battery life while reducing power consumption. The BQ25120 has a linear charger in a single device that can configure a low pressure regulator (LDO), a load switch, a buck converter, buttons control, and a battery voltage monitor. As long as the battery voltage ranges from 3.6V to 4.65V, the fast charging current is between 5mA to 300mA, which can be applied to the BQ25120, which allows the wearable and industrial network (IoT) application to be in normal open state without consumption. Photo battery is electrically.
Features and advantages:
700NA minimum static current: B25120 can remain normally open at 1.8V operating voltage by using a power path technology and a low static current buck converter. This allows the primary microprocessor including the TI host microprocessor, the Bluetooth® RF, the SIMPLINKTM Bluetooth Smart CC2640 wireless MCU, can be taken from the "exuberable" battery during charging, thereby sustainable operation. Since this solution has 50NA standby mode quiescent current, designers can maximize battery life.
High integration: Configurable Load Switch / LDO Optimization System Close the rare features such as radios and displays, minimizing battery consumption. This solution also includes an integrated battery voltage monitor that implements charge indicators, buck converters, and button control characteristics.
Minimal Battery Management Solution Industry: 2.5mm x 2.5mm Wafer Chip Package (WCSP) in this solution can achieve smaller deposit area, which makes it easy for designers to integrate this device in the latest. Can wear design. In addition, in order to make the solution more robust and durable, designers can use CC2640 Wireless MCU solutions (this device for Bluetooth Smart applications is the industry's smallest, four-way flat-free package solutions with integrated flash memory).
Accurate charging duration of as low as 500μA: This characteristic maximizes the energy of the charging period to the battery to the battery, thereby allowing the battery to be powered on more stable and durable.
User flexibility: The I2C programming interface of BQ25120 enables designers to set key parameters such as battery charger voltage, current, termination threshold, input current limit, load switch control, flexible timer, and reset options.
To integrate more terminal application features, BQ25120 can be used with other devices. Ultra-low static current buck converters, TPS62743 can be used for additional buck output. The boost converter can also be used to display integration. TPS61046 provides 12V boosting, and TPS61240 supported on load is 5V boost for heart rate monitors or small-sized monitors.
