Allegro MicroSystems, Inc. has expanded its portfolio of three-phase sensorless BLDC gate drivers, delivering improved thermal efficiency for lower energy use and data-center costs. The new A89332 and A89332-1 offer new options that meet the requirements of cooling systems in today’s data centers. Available with integrated power loss brake (A89332) and AC-loss (A89332-1) features, these gate drivers enable small high-airflow fan designs to improve thermal efficiency. “When server fans malfunction or break, backflow causes them to go into reverse rotation, the other fans have to work harder to compensate for the resulting airflow, which increases power consumption,” said Allegro. A traditional solution to prevent the reverse rotation is adding external circuitry and components, which don’t fit into 1U fans, to function as the power loss brake, added the company. This adds software coding, in addition to the increased bill of materials and time to market. Allegro said the A89332’s integrated power loss brake (PLB) function stops the fans from spinning, with braking performance that is four times better than discrete implementations, eliminating unnecessary power consumption and increasing thermal efficiency. When combined with the A89332-1’s AC loss logic, the solution claims the industry’s smallest gate driver, in a 26-contact, 4 × 4-mm QFN package that is 36% smaller than comparable options. These packages are lead (Pb) free, with 100% matte-tin leadframe plating.

Efficient Power Conversion Corporation (EPC) has expanded its selection of low voltage, off-the-shelf gallium nitride (GaN) transistors with the introduction of the EPC2066 (0.8 mΩ typical, 40 V) GaN FET. EPC calls the EPC2066 the smallest 40 V, 1.1 mΩ FET, with an ultra-small 13.9 mm² footprint. The low losses and small size makes the device suited for the secondary side of high-power-density DC/DC converters for servers and artificial intelligence. It also can be used for the secondary side synchronous rectification to 12 V in power-supply and silver-box data-center servers, and for high-density motor-drive applications from 24 V – 32 V. The EPC2066 is footprint compatible with EPC’s Generation 4 product, the EPC2024. The Generation 5 improvement in area × R_DS(on) gives the EPC2066 a 27% reduction in on-resistance in the same area, said EPC. The EPC9174 reference design board, a 1.2-kW, 48-V input to 12-V output LLC converter, features the EPC2071 for the primary side full bridge and the EPC2066 on the secondary side. The EPC2066 eGaN FET is priced at $3.75 each at 1K units/reel. The EPC9174 development board is priced at $780 each. The EPC2066 and EPC9174 demonstration board are available from Digi-Key.

Vishay Intertechnology, Inc. has introduced a new high-energy wet tantalum capacitor for military and avionics systems. The company said it delivers the industry’s highest capacitance per voltage rating and case size for this device type. The EP2 capacitors, built on Vishay’s SuperTan technology, offers ultra-high capacitance from 2,700 µF to 48,000 µF in the B case code and 3,600 µF to 72,000 µF in the C case code. Voltage ratings range from 25 VDC to 125 VDC. The EP2’s industry-leading values include a capacitance of 9,000 µF at 80 V and 58,000 µF at 35 V in the C case size. Vishay said these values are 50% and 21% greater, respectively, than the closest competing device. The standard capacitance tolerance is ±20%, with ± 10% tolerance available. The capacitor also features high vibration (high frequency: 20 g; random: 19.64 g) and mechanical shock (50 g) capabilities. The operating temperature range is -55°C to 85°C, and to 125°C with voltage derating, and provides maximum equivalent series resistance (ESR) down to 0.017 Ω at 1 kHz and 25°C. “Available with radial through-hole terminations with a stud-mount option in the B and C case codes, the EP2 can be used as an exact drop-in replacement for competing parts or as a higher capacitance alternative in a mechanically-equivalent package to reduce component counts, save space, and lower design costs,” said Vishay. Samples and production quantities are available. Pricing for U.S. delivery starts at $750 per piece.
