Wed, 16 Jul 2008 08:00:00 UT Allegro MicroSystems Europe http://www.electronicstalk.com/news/alb/alb278.html Third-generation automotive-grade three-phase MOSFET predriver is ideal for systems that use sinusoidal control of the motor phase currents. Wed, 09 Jul 2008 08:00:00 UT Allegro MicroSystems Europe http://www.electronicstalk.com/news/alb/alb277.html The A3942 is designed to drive four N-channel MOSFETs in a high-side configuration with gate drive outputs that use a current-source topology, eliminating the need for bootstrap capacitors. Wed, 18 Jun 2008 08:00:00 UT Allegro MicroSystems Europe http://www.electronicstalk.com/news/alb/alb276.html Dynamic offset cancellation reduces the residual offset voltage normally caused by device package overmoulding. Wed, 04 Jun 2008 08:00:00 UT Allegro MicroSystems Europe http://www.electronicstalk.com/news/alb/alb275.html A precise, proportional voltage is provided by the low-offset, chopper-stabilised BiCMOS Hall IC, which is programmed for accuracy at the factory. Wed, 28 May 2008 08:00:00 UT Allegro MicroSystems Europe http://www.electronicstalk.com/news/alb/alb274.html The automotive market is looking to new technologies to replace belt-driven and hydraulic actuators with more efficient systems. Wed, 21 May 2008 08:00:00 UT Allegro MicroSystems Europe http://www.electronicstalk.com/news/alb/alb273.html Each BiCMOS monolithic circuit integrates a Hall-effect sensor element, temperature-compensating circuitry to reduce the intrinsic sensitivity drift of the Hall element. Wed, 14 May 2008 08:00:00 UT Allegro MicroSystems Europe http://www.electronicstalk.com/news/alb/alb272.html The A1172 can easily replace reed switches, providing superior reliability and ease of manufacturing while eliminating the requirement for signal conditioning. Wed, 07 May 2008 08:00:00 UT Allegro MicroSystems Europe http://www.electronicstalk.com/news/alb/alb271.html The A1444 and A1445 employ a soft-switching algorithm to reduce audible switching noise and EMI interference. Thu, 01 May 2008 08:00:00 UT Allegro MicroSystems Europe http://www.electronicstalk.com/news/alb/alb270.html The A1351 linear Hall-effect sensor IC converts an analogue signal from its internal Hall sensor element to a digitally encoded PWM output signal. Thu, 24 Apr 2008 08:00:00 UT Allegro MicroSystems Europe http://www.electronicstalk.com/news/alb/alb269.html The A4490 uses multiphase switching to reduce electromagnetic interference and minimise stress on the input capacitors by interleaving the turn-on cycle of the regulators. Wed, 16 Apr 2008 08:00:00 UT Allegro MicroSystems Europe http://www.electronicstalk.com/news/alb/alb268.html 16-channel LED driver is easy to cascade for larger-scale display applications. Fri, 04 Apr 2008 08:00:00 UT Allegro MicroSystems Europe http://www.electronicstalk.com/news/alb/alb267.html The Hall sensor inputs can be driven directly by a microprocessor, which makes the A3930 and A3931 key components in a robust sensorless back-EMF solution. Thu, 27 Mar 2008 08:00:00 UT Allegro MicroSystems Europe http://www.electronicstalk.com/news/alb/alb266.html Each of the A6285's 16 channels individually adjusted from 0 to 100% of the maximum value via the dot correction register. Thu, 06 Mar 2008 08:00:00 UT Allegro MicroSystems Europe http://www.electronicstalk.com/news/alb/alb265.html Sensor ICs provide a voltage output that is directly proportional to an applied magnetic field. Tue, 26 Feb 2008 08:00:00 UT Allegro MicroSystems Europe http://www.electronicstalk.com/news/alb/alb264.html High-brightness constant-current LED driver IC is designed to operate over typical automotive voltage and temperature ranges, running from inputs from 6 to 40V.
