The new A3987 from Allegro MicroSystems Europe is a microstepping motor driver IC which combines an output drive capability of 50 V and ±1.5 A with built-in translator circuitry and overcurrent protection. The new device is designed to operate bipolar stepper motors in full, half, quarter and sixteenth step modes, and includes a fixed off-time current regulator which has the ability to operate in slow or mixed decay modes. Typical applications ...

Applied Power Systems' SixPac series of integrated inverter power stages for energy conversion, frequency conversion, motor drives and similar applications, are said to ensure a reduction in time for t new product development.

UNIPOWER announces a new modular, four output power supply series designed to give up to 400W via outputs in the range 3.3 to 48VDC. This level of power and range of output voltages makes the new power supplies suitable for a wide range of applications.

Linear Technology has announced the LT3481, a 2A, 36V step-down switching regulator with Burst Mode operation to keep quiescent current under 50uA. The LT3481 operates within a VIN range of 3.6V to 34V, making it ideal for load dump and cold-crank conditions found in automotive applications. Its 3.2A internal switch can deliver up to 2A of continuous output current to voltages as low as 1.26V.

MicroPower Direct, is pleased to announce the release of the D200RU series. Featuring an ultra-wide 4:1 input voltage range, this miniature series of 2W SIP converters provides miniature packaging, tight output regulation, 1,000 VDC input/output isolation and low cost.

The smallest 1U Height, 320W AC/DC power supplies available. These safety approved supplies feature power factor correction, autoranging AC inputs, robust filtering, 100 kHour MTBF and four mechanical options.

Universal Voltronics’ line of BRC switching power supplies are notable for low ripple, fast transient response, endurance to repetitive arcing and stable output even in the face of line voltage and load charges. Power is converted using advanced IGBT’s switching at frequencies above 20kHz, and controlled using tuned pulse width modulation techniques.

The new A8698 and A8697 from Allegro MicroSystems Europe are the latest additions to the company's range of step-down regulator ICs.

HiTek Power has introduced the OL6000/803, an 80kV power supply for applications ranging from ion implantation to electron-beam welding to particle acceleration. The robust new supply is housed in two 4U high, 19-inch rack-mounting chassis weighing a total of 80kg, making it one of the smallest and lightest in the industry for its output.

Texas Instruments Incorporated today introduced several new battery management integrated circuits (ICs), including its next-generation Impedance Track™ “gas gauge” chipset, to improve battery performance and protect multi-cell, lithium-based battery packs used in notebooks and other systems.
