ST's new charger chip integrates energy management for wearable and portable devices
ST's new battery charge management chip greatly improves functional integration, with no impact on charging performance and power consumption. The highly integrated STBC02 chip incorporates the most common features required for energy management in wearable and portable devices, including linear battery charging, 150mA low voltage drop regulators, two SPDT(single/double throw) load switches, intelligent reset/watchdog functions, and a protective circuit module to prevent battery damage from misoperation.
According to independent market research firm IDC[1], the wearable device market reached 78 million units in 2015, with a year-on-year growth rate of 172%. STBC02 brings a comprehensive charge management solution to this dynamic market for a wide range of health, fitness, communication and social wear products, reducing application space, simplifying design, reducing costs, and accelerating time-to-market.
The full functionality of the STBC02 is controlled by the SWIRE protocol and requires only one microcontroller I/O pin, while providing longer battery life for target applications with extremely low upcurrent.
Important features of the new product include:
Built-in protection circuit module, so that the new product can be used directly with the battery, without any other protection chip;
The built-in power channel charges the battery and supplies the entire system;
Built-in intelligent reset/watchdog timer, improve the professionalism of the system, when the software fails, all functions can be restored;
Adjustable Vbatt no-load voltage, different lithium batteries can be used to implement customized charging strategies;
10nA Off mode current for extended battery life Provides on-demand battery monitoring for the system controller.
