The TPS92640/1 are 85 V input voltage, adjustable frequency, synchronous buck dc/dc LED controllers that accept analog and PWM inputs resulting in dimming ratios of 500:1 and 2500:1, respectively....More
Utilizing a proprietary Impedance Track algorithm, the gauge constantly informs a user about the battery’s state-of-health and state-of-charge and maintains up to a 95% accurate capacity measurement for the entire life of the battery....More
Chris Oberhauser let the sparks fly at APEC 2013 with a demonstration that uses TI's C2000 MCU and analog signal components to detect arcing events in solar and other high-voltage DC applications....More
The driver also features a smart loop architecture that claims to reduce startup and braking time by half, deliver twice the vibration strength, and consume 50% less power....More
Although external RC filters aren’t necessarily required to achieve an effective ratiometric measurement, adding external filters may prove to be beneficial in applications where the RTD sensor is located remotely in a noisy environment or where sensors are prone to noise pickup....More
The IC’s fast-charge circuits reduce charge time through battery path impedance compensation, and offer programmable thermal management capability to ensure safe, reliable system operation and improve system-level design....More
LED market penetration will continue to grow as costs decline and efficiencies improve. Thermal design of the LED system will play a vital role in providing reliable operation and in finding the lowest-cost cooling solutions....More
Today's automobiles use up to a hundred microprocessors that control every aspect of their performance. Large amounts of data must be moved over inexpensive wire in a harsh environment, presenting many challenges....More
