SMART TECH & IOT
Advanced Battery- Management ICs are Essential Elements Powering the Growth of Smart IoT Devices
New battery-protection system approach integrates a low-leakage, low-on-resistance load switch that extends all-important battery life while saving space. Eileen Ni Sun, Founder & CEO, GLF Integrated Power
T
he term Internet of Things, or IoT, was fi rst developed in the late 1990s and was related to RFID technology. Over the two decades since being developed, IoT has fl ourished to include literally billions of nodes, each with its unique IP address. The notion of “smart” IoT is a relatively new development. These IoT devices are designed to create intelligent, interconnected systems to gather, process and utilise data to make informed, intelligent decisions. Adding intelligence to IoT devices requires the utilisation of microcomputers, memory, communications modules like Bluetooth and other components. Please refer to Figure 1 for example of smart IoT applications. One thing all smart devices have in common is the increased power needed to perform these numerous functions; thus, more reliable and long-lasting battery power is essential in smart IoT applications. A critical tool in achieving extended battery life is the implementation of advanced battery- protection systems.
The Traditional Portable Battery- Protection Systems
In recent years, the demand for portability of sophisticated electronic systems has driven the need for various types and sizes of battery systems. These battery systems were used to power laptops, mobile phones, digital cameras, and portable digital assistants (PDAs). Using a variety of battery chemistry materials, such as nickel metal hydride, lithium-ion, and lithium polymer, could deliver more than 1A of continuous current. As IoT applications proliferated, design challenges arose as portable devices increasingly required better protection of battery systems to prevent such problems as overcharge, overdischarge or excessive
