| 600-V GaN FET Power Stages Support up to 10kW
Texas Instruments (TI) has announced a new portfolio of ready-to-use, 600-V gallium nitride (GaN), 50-mohm and 70-mohm power stages to support applications up to 10 kW. The LMG341x family enables designers to create smaller, more efficient and higher-performing designs compared to silicon field-effect transistors (FETs) in AC/DC power supplies, robotics, renewable energy, grid infrastructure, telecom and personal electronics applications.
TI's family of GaN FET devices provides a alternative to traditional cascade and stand-alone GaN FETs by integrating unique functional and protection features to simplify design, enable greater system reliability and optimize the performance of high-voltage power supplies.
Dubbed the LMG3410R050, LMG3410R070 and LMG3411R070 TI's integrated GaN power stages double power density and reduce losses by 80 percent compared to silicon metal-oxide semiconductor field-effect transistors (MOSFETs). Each device is capable of fast, 1 MHz switching frequencies and slew rates of up to 100 V/ns.

Transceivers Ease HD Video Upgrades Using Existing Vehicle Cabling
Analog Devices has announced a transceiver series that enables high-definition (HD) video over existing unshielded twisted pair cables and unshielded connectors. This allows OEMs to upgrade easily from standard-definition cameras to HD cameras and provide the superior resolution and image quality required for today's automotive camera applications. The new ADV7990 and ADV7991 transmitters and ADV7380 and ADV7381 receivers use ADI's Car Camera Bus (C2B) technology to enable significant savings in weight, bulk, cost and reduce cable-routing constraints when compared to other automotive link solutions, according to ADI. The C2B transceivers are defined and designed specifically for automotive applications, which means that along with supporting excellent visual quality over the unshielded infrastructure, significant care was also taken with on-chip EMC/EMI mitigation techniques enabling full compliance to the rigorous industry mandates for EMC, EMI and ESD robustness. The performance of the cable-compensation design supports 30-meter cable runs with multiple in-line connections for resolutions up to 2 megapixels at 30 Hz or 1 megapixel at 60 Hz.

Full-Bridge 600V/3.5A Power Driver Features SiP Format STMicroelectronics' has released its PWD5F60 high-density power driver, the second in a new series of power driver systems-in-package (SiP) addressing high-voltage brushed DC and single-phase brushless motor applications. It integrates a 600V/3.5A single-phase MOSFET bridge with gate drivers, bootstrap diodes, protection features, and two comparators in a 15 mm x 7 mm outline. The thermally efficient system-in-package occupies 60% less board real-estate than discrete components, while boosting reliability and simplifying design and assembly.
As a single-phase full-bridge module, the PWD5F60 is tailored for driving brushed DC motors in applications such as industrial pumps and fans, blowers, domestic appliances and factory-automation systems. It is particularly targeted at appliances using single-phase brushless motors. Such motors provide high durability and efficiency at a reasonable cost. The chip is also cost-effective and convenient for use in power supply units. With on-resistance of 1.38 ohms, the PWD5F60's integrated N-channel MOSFETs ensure high efficiency for handling medium-power loads.
