Maxim Integrated Products (PINK OTC MARKETS: MXIM) introduces the MAX16054, a pushbutton on/off controller with debounce circuitry and ±15kV ESD protection. This device features state memory that causes the output state to latch after the switch is released/opened, thereby allowing normally open switches to act as on/off switches. Enabling simpler, lower-cost switches with on/off capability, the MAX16054 is ideal for handheld devices, portable electronics, set-top boxes, portable instrumentation, and white goods.

The MAX16054 is a highly durable device designed to withstand harsh operating conditions. Its integrated switch-debounce circuitry allows the device to accept a noisy input from a mechanical switch and produce a clean, latched digital output signal. This increases reliability and reduces design time compared to alternate solutions. To further increase reliability, the MAX16054 is rated to withstand up to ±15kV of ESD, providing essential protection for applications involving an end-user interface. Moreover, the switch’s input features overvoltage clamping diodes that allow the device to handle voltage swings of ±25V to ground.

The MAX16054 consumes only 7µA of quiescent current. It is available in a small, 6-pin thin-SOT23 package, and is fully specified over the -40°C to +125°C automotive temperature range.

Maxim Integrated Products is a publicly traded company that designs, manufactures, and sells over $2 billion of high-performance semiconductor products annually. It was founded over 25 years ago with the mission to deliver innovative analog and mixed-signal engineering solutions that add value to its customers’ products. To date, Maxim has developed over 5700 products serving the industrial, communications, consumer, and computing markets. For more information, go to www.maxim-ic.com.

Plano, TX — Texas Advanced Optoelectronic Solutions Inc. (TAOS) announced the industry’s first dual-source agreement for ambient light sensors with Avago Technologies. The two companies worked together in joint recognition of the growing demand for second sourcing of ambient light sensors used in high-volume display applications, such as cell phones, computer monitors and LCD displays.

According to the terms of the agreement, the two companies will provide a true dual source for a family of ambient light sensors that combine the TAOS light-sensing circuit-design technology with Avago’s packaging technology. Dual sourcing will benefit this growing high-volume market because the products will come from completely independent supply chains, from the wafer processing to the final testing of the product.

“Ambient light sensor technology is one of the attractive methods to reduce the liquid crystal display power consumption,” said Jennifer Colegrove, Senior Analyst at iSuppli Corp., who authored the iSuppli Low-Power and Zero-Power Display report. “It adaptively dims the backlight in response to ambient luminance to provide low power consumption and good readability. Low power consumption displays mean longer battery life for mobile devices. At iSuppli, we see more and more mobile handsets and notebook computers are adopting the use of ambient light sensors. For example, Apple’s iPhone has a built-in ambient light sensor for power saving.”

The first dual-source device resulting from this agreement is TAOS part number TSL2563CL or Avago part number APDS-9300. This is a Digital Ambient Light Sensor with I2C interface packaged in a 6-pin ChipLED surface mount package measuring 2.6 mm by 2.2 mm and is well-suited for use in LCD monitors, flat-panel televisions and cell phones.

“TAOS is proud to join Avago Technologies in the very first dual-source agreement for ambient light sensors that is a form, fit and function drop-in replacement,” said Kirk Laney, President and CEO of TAOS Inc. “The combination of the Avago innovative packaging technology with the TAOS world-class leadership in light sensing technology makes for a winning team. Moreover, it is additional proof that integrated optoelectronics, traditionally considered a niche technology, has now taken its place in the mainstream electronics marketplace.”

“Avago Technologies believes that the combined strengths of the two companies makes this dual-source agreement a natural fit to meet ongoing customer needs,” said Tze-Siong Chong, Vice President & General Manager, Optical Communications Solutions Division, Avago Technologies. “We are pleased to be working with TAOS, Inc. and are confident that this ambient light sensing dual-source agreement will be a win-win situation for Avago and TAOS as we meet the growing needs of our customers.”

Maxim Integrated Products (PINK OTC MARKETS: MXIM) introduces the MAX13046E/MAX13047E ±15kV ESD-protected, single-/dual-channel, bidirectional level translators. Designed to provide level shifting for data transfer in multivoltage systems, these devices accept a VL voltage from 1.1V to either 3.6V or (VCC + 0.3V), whichever is lower, and a VCC from 1.65V to 5.5V. Over these specified voltage ranges, the MAX13046E/MAX13047E operate at a guaranteed data rate of 8Mbps; within specific voltage domains, higher data rates are possible. Integrating ±15kV ESD-protection circuitry in tiny µDFN, TDFN, and UTQFN packages, these devices save board space while providing enhanced protection for applications that route signals externally. Consequently, the MAX13046E/MAX13047E are ideal for data transfer between low-voltage ASICs/PLDs and higher-voltage systems.

The MAX13046E/MAX13047E also feature thermal short-circuit protection and a shutdown mode that reduces the supply current to less than 1µA. Fully specified over the -40°C to +85°C extended temperature range, the MAX13046E is available in a 1mm x 1.5mm, 6-pin µDFN package, while the MAX13047E is available in 2mm x 2mm, 8-pin TDFN and tiny, 1.4mm x 1.8mm, 10-pin UTQFN packages. Prices start at $0.90 (1000-up, FOB USA).

Maxim Integrated Products (PINK OTC MARKETS: MXIM) introduces the MAX9744, the industry’s first 20W stereo Class D speaker amplifier to operate from a 4.5V to 14V power supply. The wide supply range minimizes the cost of portable designs by reducing component count and allowing the use of a smaller battery pack. The MAX9744 provides ample output power throughout the power-supply voltage range, making it ideal for MP3 docking stations, gaming consoles, and flat-panel televisions.

Additionally, the MAX9744 integrates 64-step analog and digital volume control. In analog mode, the volume range is ratiometric relative to VDD. To ramp up or down the volume digitally, the system microcontroller can program a 6-bit register through the MAX9744’s I²C interface.

External feedback resistors set the input gain, while the output has an internally set gain. When powered from a 12V supply, the MAX9744 combines these gains with the wide volume-control range, and delivers 20W per channel into 4Ω speakers.

Class D amplifiers are known for high power efficiency, and the MAX9744 does not disappoint with its 93% efficiency while delivering 20W into an 8Ω load. Achieving high 75dB PSRR, low 0.04% THD+N, and greater than 90dB SNR, this stereo amplifier offers Class AB performance with Class D efficiency.

Due to the switching nature of the output stage, most Class D amplifiers require large, costly output filters; exhibit poor THD+N; and radiate electromagnetic interference (EMI). The MAX9744, however, employs Maxim’s patented spread-spectrum modulation* to reduce the peaks of the fundamental and subsequent harmonics by spreading energy over a wider bandwidth. This device also offers a filterless modulation mode, which eliminates the large LC filters required by traditional Class D amplifiers. These two modulation schemes minimize design cost and space, and they eliminate the time-to-market problems associated with EMI radiation.

Hamamatsu Photonics K.K. has successfully oscillated the world’s first AlGaN (aluminum gallium nitride) laser diode to emit ultraviolet light at 342 nanometers*, the shortest wavelength for an electrically-driven laser diode. This breakthrough will advance the practical application of UV laser diodes in a variety of fields, including biology and environmental science. Laser diodes in general are convenient, compact devices which have low power consumption and long lifetimes, and are environmentally friendly.

Hamamatsu’s achievement will be covered in an article in the September issue of Nature Photonics, a specialty publication of U.K. scientific journal Nature. From July 27 London time, this article will be available in the “advance online publication” section of the Nature Photonics website (see link below).
