Notebook personal computer products require a varied range of LED lighting solutions from LCD display LED backlight drivers to discrete LED and RGB LED indicator lamps. Kinetic Technologies lighting and display products support application requirements from low cost compact and full size to full featured laptop computing devices.
Kinetic Technologies’ EMI/ESD Suppression solution is the industry’s first of a kind, integrating ESD and Common Mode EMI suppression IC to improve EMC performance in Ethernet applications. It is built around Kinetic Technologies’ patented and proprietary Active EMC suppression technology to enable a “Design for Compliance” approach to system design right from the start. This product helps eliminate EMC compliance challenges by providing consistent EMC performance and improvements utilizing silicon-based technology as opposed to passive technologies. EMI/ESD suppression by Kinetic Technologies enables system designers to comply with:
CISPR22 and FCC Part 15, Class B requirements?for Radiated and Conducted Emissions
IEC 61000-4-3/6 requirements for Radiated and Conducted Immunity, Level 3 or higher
Quad Channel Active EMI & ESD Suppressor for Ethernet Applications
Kinetic Technologies’ general-purpose input/output (GPIO) technology is low voltage and offers general purpose expanders designed for microcontrollers when additional I/Os are needed, ensuring additional interconnections are kept to a minimum.
As an input, the expander programs the polarity, latch, pull-up, pull-down and interrupt functions. For a system with noisy input, our GPIO technology also provides a seamless debounce function with programmable debounce time. Working as an output, this technology can?program output stage with bank/pin selectable push-pull or open-drain options, and can also program four drive strengths of the output stage to optimize rise/fall times.
GPIO technology is the perfect fit for notebooks and desktop computers.
Notebook computer display backlights require multiple white LEDs and consume the most significant portion of the device battery power budget. Multiple current sink drivers connect to long serial strings of WLEDs and therefore require a compliance voltage significantly higher than the battery voltage.
Panel size and resolution determine the number of white LEDs (WLED) required to produce the necessary screen brightness
Dimming techniques to control the brightness can range from simple linear LED brightness control to sophisticated high efficiency PWM control to achieve contrast ratios of typically 20,000:1
High accuracy current sinks to provide uniform backlight across larger panel sizes
High efficiency boost power conversion required to minimize demands on battery power consumption and maximize the battery life between charge cycles
Multiple series/parallel strings of WLED drivers to match the display panel needs
Multiple programming options from simple PWM signal control to full-featured I2C interfaces.
Advanced design, low drop-out current sinks with tight linearity characteristics to maintain constant LED current accuracy over all battery voltage extremes
High efficiency boost converters with integrated protection against LED open and short-circuit conditions
6-Ch Step-Up LED Driver with PWM-Control Mixed-Mode Dimming, low duty dimming
Overvoltage and Surge Protection ICs
Overvoltage and Surge Protection ICs are used to isolate, manage and protect systems. The devices are used to turn power off and on to downstream system loads. Common purposes for using Overvoltage and Surge Protection ICs include: protecting low voltage circuitry from abnormal power supply conditions, such as mains power surges or incorrect charger adapters, conserving energy when not required or safely turning on loads to prevent system voltage or current spikes.
Overvoltage and Surge Protection ICs are used in notebooks and utilize low resistance switches that apply to a broad selection of notebook products.
