AEC-Q101-qualified p-channel MOSFET offers ON-resistence down to 30 mΩ
Vishay Intertechnology, Inc. today introduced a new AEC-Q101 qualified p-channel -100 V TrenchFETMOSFET designed to increase power density and efficiency in automotive applications. Not only is the Vishay Siliconix SQJ211ELP the industry’s first such device in the compact 5 mm by 6 mm PowerPAK SO-8L package with gullwing leads, but it also features best in […]
80 V RETs feature overhead to handle spikes and pulses
Nexperia announced the industry’s first 80 V RET (Resistor-Equipped Transistor) family. These new RETs or ‘digital transistors’ provide enough headroom for use in 48 V automotive board net (e.g. mild hybrid and EV cars) and other higher voltage circuits which are often subject to large spikes and pulses that previous 50 V parts cannot handle. […]
Single-/Multi-cell solar harvester increases runtime in wearable and IoT applications
Designers of space-constrained designs can now significantly increase runtime with the MAX20361 single-/multi-cell solar harvester with maximum power point tracking (MPPT) from Maxim Integrated Products, Inc. . The industry’s smallest solar harvesting solution is ideal for space-constrained applications such as wearables and the emerging internet of things (IoT) applications. Designers are often challenged with the […]
Half-bridge PCBs help evaluate GaN drivers, transistors
GaN Systems announced the release of two 650V half-bridge daughter cards (30A and 60A), which provide an ultra-versatile platform to evaluate GaN drivers and transistors. The evaluation cards are available in two power levels, up to 3kW (GS-EVB-HB-66508B-RN) and up to 6kW (GS-EVB-HB-66516T-RN), and include the Renesas RAA226110 low-side GaN FET driver. These cards are the industry’s […]
SiPs combine two GaN HEMTs, high-voltage gate drivers
Building upon the advantages of STMicroelectronics’ MasterGaN platform, MasterGaN2 is the first in the new family to contain two asymmetric gallium-nitride (GaN) transistors, delivering an integrated GaN solution suited to soft-switching and active-rectification converter topologies. The 650V normally-off GaN transistors have on-resistance (RDS(on)) of 150mΩ and 225mΩ. Each is combined with an optimized gate driver, making GaN […]
Reference design lets secondary MCU control primary power
In modern offline AC-DC power solutions, programmability and adaptive control offer the flexibility and intelligence needed by smart home devices to better interface with their power systems. In these systems, a secondary side microcontroller (MCU) is typically not capable of starting a system without the use of a separate bias power supply. A new reference […]
High-temperature snubberless triacs reduce heat sink needs
STMicroelectronics’ 800V 8H Triacs operate at full rated current up to the maximum junction temperature of 150°C, allowing heatsinks in drives for AC loads to be up to 50% smaller to combine compact dimensions with high reliability. Suited to industrial, personal care, smart-home, and smart-building applications, the new Triacs leverage ST’s latest Snubberless high-temperature technology […]
Single IC integrates power, voltage, and current monitoring, reinforced isolation
Allegro MicroSystems announced the launch of the ACS37800, a Hall-effect power monitoring IC for single-phase AC and DC solutions in a small PCB footprint. Another industry-first innovation, Allegro’s ACS37800 is an integrated power monitoring chip that allows simultaneous measurement of power, voltage, and current for AC and DC signals with an isolation rating of up […]
High-temp, high-ripple current capacitor yields long life
New Yorker Electronics has announced the release of the new Vishay BC Components 190 RTL Aluminum Capacitors for increased design flexibility and board space in high-temperature applications. The new Automotive Grade miniature aluminum electrolytic capacitors offer high ripple currents up to 3.36A, operating temperatures to +125°C, and up to 6,000 hours of usable life. […]
