Shanghai-based WeEn Semiconductors unveiled 650V and 1,200V IGBTs with fast recovery anti-parallel diodes at PCIM in Nuremberg. “Based on fine trench gate field-stop technology, the IGBTs provide a more uniform electric field within the chip, support higher breakdown voltages and offer improved dynamic control,” according to the company. “A positive temperature coefficient simplifies parallel operation.” Ratings are 650V 75A, 1.2kV ...

Novosense Microelectronics announced a 24 channel automotive LED driver at PCIM in Nuremberg today. NSL21924 is a high-side driver, aimed at rear lights, exterior lights and general automotive interior and body lighting. 16 channel NSL21916 is also available. Qualification is to AEC-Q100 Grade 1 (Tj = -40 to +150°C). The LED supply voltage can be across 3 to 16V, and ...

Texas Instruments introduced a 450V intelligent power module that includes a GaN three-phase bridge for motors up to 250W. Called DRV7308, it can stand-off 650V and handle pulses up to 5A. Inside its 12 x 12mm QFN package and six 205mΩ hemts (at 25°C ambient), drivers and protection component, and it is capable of implementing inverters with >99% efficiency, according ...

Qorvo has picked depletion-mode (normally-on) silicon carbide JFET technology to build a 750V 4.3mΩ transistor for circuit breakers, and put it in a 10 x 12mm surface-mount TOLL package. “It was designed for circuit protection applications including solid-state circuit breakers, where low resistance, thermal performance and reliability are paramount,” according to the company. This “JFET can withstand high instantaneous junction ...

EPC is aiming at USB-C PD applications 50V 8.5mΩ GaN transistor with a 1.8mm2 footprint. EPC2057 measures 1.5 x 1.2mm and can handle 9.6A continuously (25°C) and 66A single 300µs pulses (25°C). With such a tiny package, thermals are important. According to the data sheet, junction-to-case thermal resistance is 2.3°C/W, then it is 7°C/W junction-to-board, 72.5°C/W junction to ambient on ...

Microchip has turned to silicon carbide to create a bi-directional electric vehicle on-board charger design for 400V or 800V batteries. There are two halves: a 7.6kW bi-directional two-phase interleaved totem-pole power factor corrector, and an 11kW dual full bridge transformer-coupled bi-directional dc-dc converter. “These two designs work together,” Microchip told Electronics Weekly. “At PCIM we showed both operating in bi-directional ...

Cambridge GaN Devices (CGD) has teamed up with Qorvo to build a GaN-based evaluation kit for controlling brushless-dc and permanent magnet synchronous motors. From Qorvo comes its PAC5556A motor control IC that combines a 150MHz Arm Cortex-M4F processor and 128kbyte of flash, with 600V gate divers, PWMs and multi-chanel data conversion. CGD is providing its IC-based GaN power hemts that ...

SemiQ will unveil 1,200V silicon carbide half-bridges packaged in S3 modules at PCIM next month. The industry-standard package is 62mm long and 26.3mm high. So far, only the part numbers and basic specs have been revealed: GCMX003A120S3B1-N 600A 3mΩ GCMX005A120S3B1-N 400A 4.5mΩ They will be aimed at induction heaters, welding equipment, uninterruptible power supplies photovoltaic inverters, wind inverters, energy storage, ...

EPC is aiming at eMobility, forklifts and high-power drones with a 150Arms brushless motor driver design using its GaN power transistors. Documents for EPC9186, as it will be known, are not available yet, but the company promises operation from 14V to 80V for “applications such as electric scooters, small electric vehicles and agricultural machinery” in addition to the items above. ...

Texas Instruments is aiming at electric vehicle traction inverters with a functional safety-compliant isolated gate driver for silicon carbide mosfets and IGBTs. Called UCC5880-Q1, it is in pre-production and the full data sheet has not yet been made public. One novel feature that has been revealed is that the device has two parallel high-side drivers and two parallel low-side drivers ...
