b2ap3_thumbnail_1115_TI_Glaser_F1.gifSTMicroelectronics has extended its range of high-side current-sensing portfolio with the TSC102 that simplifies design of smarter and safer systems by sensing current more accurately and giving designers extra flexibility to adjust the sensor's output before inputting to the system controller. The amplifiers provide a fully configurable integrated signal-conditioning amplifier that target automotive, industrial and computer applications.

Accurate sensing of system current is central to effective control of precision equipment performing functions such as positioning, variable-speed operation, or continuous self optimization to maximize energy efficiency. Precision current sensing is also important in a wide variety of safety mechanisms, such as auto-stop for vehicle-window lifters to prevent discomfort or injury to users.

ST's TSC102 is designed for direct connection to a small current-sensing resistor sitting at a voltage up to 30V. This direct connection allows a system to be monitored without disturbing its ground connection, which is essential in applications like automotive systems or for monitoring power supplies with multiple outputs. The device also has rugged inputs to survive applied voltages ranging from -16V to 60V. These voltages can arise in systems where many loads are switching continuously or there is a risk of a reverse battery connection, such as in vehicle electrical infrastructures.

b2ap3_thumbnail_9TpdK4aTE.gifChip design costs are expected to shoot up, but software—not hardware—is playing a much greater role in the problematic equation.

This is according to Mentor Graphics Corp. chairman and CEO Walden Rhines, who said that the shift in the equation will require a new type of EDA technology—embedded software automation (ESA)—as a means to attack the problem.

Rhines warned that IC design costs for many devices are projected to hit the dreaded $100 million level within the next three years. Not long ago (and even today), IC design costs ranged between $20-to-$50 million.

offering a custom silicon and software intended to streamline the design process for e-books using the same E-Ink display. 

TI's chips and software also are intended to allow OEMs to lengthen the battery lifetime of their e-books by 50 percent while shrinking the footprint by eliminating 40 discrete components.

"We are offering a comprehensive e-book development platform to e-book developers that will speed their time to market, lower their BOM, shrink their footprint by 200 square millimeters and increase their battery lifetime by about 50 percent," claimed Gregg Burke, TI's eBook business line manager.
