Linear Technology has announced the LTC4358, a single high voltage ideal diode controller utilizing an internal 5A MOSFET to provide a simple, low loss replacement to Schottky diodes in high current applications. The controller and 20m Ohm internal N-channel MOSFET perform the function of a low forward voltage diode. This provides a lower loss path compared to the Schottky diode that in high current applications provides higher efficiency and pre...

Linear Technology announced a new high reliability MP-grade version of the LT1431, a three-terminal adjustable shunt voltage regulator that operates over a -55°C to 150°C junction temperature range. This device has a 100mA sink capability, 0.4% initial reference voltage accuracy and a ±1.4% maximum voltage drift over temperature. On-chip divider resistors allow the LT1431 to be configured as a 5V shunt regulator. By adding two exte...

Linear Technology has announced the LT3494/A low noise boost converters with integrated power switches, Schottky diodes and output disconnect circuitry. The LT3494 uses a 180mA switch, the LT3494A uses a 350mA switch, and both parts are packaged in a 3mm x 2mm DFN-8 package. Their wide 2.3V to 16V input voltage range enables operation from single cell Li-Ion batteries up to fixed 12V input rails, delivering outputs up to 40V. The LT3494 can deliv...

Linear Technology Corporation présente le LTC4359, un contrôleur à diode idéale, de forte tension, qui permet le remplacement simple, à moindres pertes, des circuits à diodes Schottky, avec les caractéristiques clés orientées vers les applications de l’automobile, l’avionique aussi bien que solaires.

Linear Technology présente le LTC4353, un double contrôleur à diodes idéales, de 0V à 18V, qui remplace deux diodes Schottky de forte puissance, et permet la réalisation de nombreuses alimentations à circuits OU, à faibles pertes, avec un minimum de perturbations pour les tensions. Le LTC4353 régule la tension directe d’un MOSFET canal N, externe, pour assurer un partage égal du courant entre les alimentations, dans les applications ...

The new A3989 from Allegro MicroSystems Europe is a high-efficiency motor driver IC designed to drive one bipolar stepper motor at up to 1.2 A and one DC motor at up to 2.4 A. The A3989 is designed for applications, typically found in office automation, automated handling equipment and gaming machines, that incorporate one DC motor and one stepper motor. The integration of two motor drivers in one compact package makes the A3989 more cost effect...
