dual DMOS full bridge motor driver IC is targeted at the office automation and
consumer and industrial markets. Designed for pulse width modulated (PWM)
control of two dc motors, the A4954 is capable of peak
output currents to ±2 A and operating voltages to 40V. Integrated charge
pump capacitors reduce external component cost and count.
terminals are provided for use in controlling the speed and direction of a dc
motor with externally applied PWM control signals. Internal synchronous
rectification control circuitry is provided to lower power dissipation during
PWM operation. Internal circuit protection includes overcurrent protection,
motor lead short to ground or supply, thermal shutdown with hysteresis,
undervoltage monitoring of VBB, and crossover current protection.
A4954ELPTR-T is provided in a low-profile 16-pin TSSOP package with exposed
thermal pad (suffix LP) that is lead (Pb) free, with 100 percent matte tin lead
frame plating. It is priced at $1.37 in quantities of 1,000.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
