Allegro MicroSystems introduced A4950, a new fully integrated single full-bridge DMOS motor driver IC with over-current protection (OCP), internal adjustable pulse-width-modulation (PWM), and a fully integrated charge pump. Allegro’s A4950 is intended for use as a DC brush motor driver with continuous output currents up to 2.5 amperes. Two input terminals are provided for use in controlling the speed and direction of a DC motor with externally applied PWM control signals.

Cypress Semiconductor unveiled a breakthrough feature for TrueTouch touchscreen controllers that enables manufacturers of handsets, cameras, GPS systems and other mobile systems to offer the benefits of capacitive touchscreens at resistive touchscreen costs. The new feature available for Cypress’s CY8CTST241 (single-touch with one-finger gestures) and CY8CTST242 (adds limited two-finger gestures such as “pinch” and “zoom”) delivers high performance touchscreen accuracy and responsiveness with a true single-layer sensor panel, drastically reducing the cost of the most expensive component of the touchscreen.
