MOSFETS
A simple and inexpensive ideal-diode MOSFET circuit
by Crutschow When you parallel a battery with another battery or other source, the batteries are often required to be back charged. This can be done with standard diodes, but that gives close to a half volt drop — even with Schottky diodes. This is especially problematic with low-voltage batteries, where that drop is a […]
600-V super-junction power modules target motor drives with new package options, features
New SLLIMM-nano intelligent power modules (IPM) from STMicroelectronics introduce extra package options and integrate additional components to accelerate development and simplify assembly of motor drives from very low power up to 300W. The 3A and 5A modules contain state-of-the-art 600V super-junction MOSFETs to maximize energy efficiency in equipment such as compressors, fans, pumps, and other appliances. A […]
New manufacturing process for SiC power devices won’t be proprietary
Researchers from North Carolina State University say they have developed a new manufacturing process and chip design for silicon carbide (SiC) power devices. The process, called PRESiCE, was developed specifcially to make it easier for companies to enter the SiC marketplace and develop new products. “PRESiCE will allow more companies to get into the SiC […]
High-speed, high-side N-channel MOSFET driver works with 60-V supplies
Analog Devices, Inc., which recently acquired Linear Technology Corporation, announces the LTC7004, a high speed, high side N-channel MOSFET driver that operates up to a 60V supply voltage. Its internal charge pump fully enhances an external N-channel MOSFET switch, enabling it to remain on indefinitely. The LTC7004’s powerful 1Ω gate driver can easily drive large […]

SOT-223 package option for 600V, 700V and 800 V MOSFETs
Infineon Technologies AG is expanding its recently launched CoolMOS P7 technology with a SOT-223 package. The device has been developed as a one-to-one drop-in replacement for DPAK. It is fully compatible with a typical DPAK footprint. The combination of the new CoolMOS P7 platform with the SOT-223 package is a perfect fit for applications such […]
Gallery: Connected car electronics on display at NXP FTF Connects in Detroit
Chip supplier NXP recently put on its two-day FTF Connects event in the Motor City. Focusing on connected vehicle and autonomous technology, featured several interesting demos and a ride in cars outfitted in V2V and V2I technology. Here are a few of the more interesting sites we found in the exhibit area and the technical […]
SiC MOSFET reference design details totem-pole PFC topology hitting 98% efficiency
Wolfspeed, a Cree Company, has advanced the development of high efficiency data center power supplies through the implementation of an innovative totem-pole PFC topology that employs its latest low-inductance SiC MOSFETs to exceed an 80+ Titanium rating, which is critical for reducing the overall power consumption for data centers, estimated to be more than 70 […]
20-V SOT-23F MOSFETs feature low on resistance
Toshiba America Electronic Components, Inc. (TAEC) has introduced four new 20V MOSFETs that feature some of the lowest on-resistance specifications in the industry. Housed in small SOT-23F packages, the SSM3K344R, SSM3K345R, SSM3J355R and SSM3J358R are suitable for lowering the power consumption in power supply controls for individual function blocks, or for power supply distribution. Applications include […]
