Circuit Protection Approach for High-Rate Discharge Li-Ion Battery Applications

Ty Bowman, Global Battery Market Manager, TE Circuit Protection, a Business Unit of TE Connectivity
In 2010, a metal hybrid PPTC (MHP) technology was introduced to address the rapidly expanding market for high-rate-discharge lithium ion (Li-Ion) battery applications. The MHP arc-less contact technology results in circuit protection devices capable of providing 30 A+ hold currents at voltage ratings over 30 VDC. <read more>

“Good Vibrations”

Upal Segupta, Staff Applications Engineer, Texas Instruments

The word “resonance” has always been interesting to me, even when I couldn’t provide an accurate definition of it. There are so many different meanings, most of which have some connection to each other. As an electrical engineer, my first reaction at hearing the word now is to think of a tuned LC circuit. <read more>

Microchip Launches 8-bit Microcontrollers with Integrated Configurable Logic in 6- to 20-pin Packages
The PIC10F(LF)32X and PIC1XF(LF)150X MCUs each feature new peripherals, including Configurable Logic Cells (CLCs), Complementary Waveform Generators (CWGs) and Numerically Controlled Oscillators (NCOs), enabling functionality that was not possible before with low pincount MCUs. These general-purpose MCUs enable designers to enhance the functionality, reduce design size, and decrease the cost and power consumption of products.



The CLC peripherals on the PIC10F(LF)32X and PIC1XF(LF)150X MCUs enable software control of combinational and sequential logic, which increases the on-chip interconnection of peripherals and I/Os, thereby reducing external components, saving code space and adding functionality. The CWG peripheral works with multiple peripherals to generate complementary waveforms with dead-band control and auto shutdown, which provides improved switching efficiencies. Additionally, the NCO peripheral enables linear frequency control and high resolution, which is required for applications such as lighting ballast, tone generation and other resonant control circuits. The MCUs also feature low power consumption, with currents of less than 30 µA/MHz in active mode, and less than 20 nA in sleep; as well as an on-chip 16 MHz internal oscillator, Analog-to-Digital Converter (ADC), and up to 4 Pulse-Width Modulation peripherals. An integrated temperature-indicator module enables low-cost temperature measurements.


To facilitate application development, the PICDEM Lab Development Kit (part # DM163045, $134.99) now includes samples of both the PIC10F322 and PIC16F1507 MCUs. Additionally, the F1 Evaluation Platform (part # DM164130-1, $39.99) is available for development with enhanced mid-range core 8-bit PIC MCUs, including the PIC1XF(LF)150X family. Also available is a free CLC Configuration Tool, to streamline the setup process of the CLC module by simulating the functionality of the registers and combinational logic in a graphical user interface (GUI).


The PIC10F(LF)320 and PIC10F(LF)322 MCUs are available in a 6-pin SOT-23 package, as well as 8-pin PDIP and 2 mm x 3 mm DFN packages. The PIC12F(LF)1501 MCU will be available in 8-pin PDIP, SOIC, MSOP and 2 mm x 3 mm DFN packages, and the PIC16F(LF)1503 MCU in 14-pin PDIP, SOIC and TSSOP packages, as well as a 3 mm x 3 mm QFN package. The PIC16F(LF)1507 MCU is available in 20-pin SSOP, PDIP, SOIC, and 4 mm x 4 mm QFN packages, as will the PIC16F(LF)1508/9 MCUs, when available. Pricing starts at $0.37 each, in 10,000-unit quantities.
