‘Fastest’ car is a hybrid

Bugatti Tourbillon

The Bugatti Tourbillon, announced yesterday, is a hybrid, with 800hp spread across three electric motors in addition to its 1,000hp 8.3 litre Cosworth V16 petrol engine. Two of the electric motors are part of the front axle system, and the other one is part of the rear axle assembly. Powered them is a 800V 25kWh oil-cooled battery housed in the ...

PCIM: 250W smart GaN motor driver is only 12x12mm

TI DRV7308 GaN smart motor power module

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 ...

Functional safety gate driver spans 24 to 60V for motors in vehicles

Infineon TLE9140 automotive gate driver

Infineon is aiming at 24 and 48V ancillary motors in vehicles, with a three-phase bridge gate driver with advanced protection features. “The gate driver IC offers functional safety according to ISO 26262 ASIL B,” according to Infineon. “It has a range of protection functions such as timeout-watchdog, drain-source monitoring, over-voltage, under-voltage, cross-current and over-temperature protection, as well as off-state diagnostics.” ...

Microcontroller, CAN and gate drivers on one IC for motor mosfets

Microchip-integrated-motor-driver-block

Microchip is aiming at motor control by combining a triple half-bridge mosfet gate driver, a 100MHz processor and CAN FD transceivers in the same IC. Other members of the family offer LIN transceivers instead of CAN, or a CAN interface without transceivers, or no CAN or LIN, and a base model has a 70MHz processor. Some have SENT interfaces for ...

FPGA motor drive starter kit for system-on-module

AMD KD240 motor drive development kit

AMD has introduced a motor driver starter kit for its Kria K24 system-on-module – which is built around a Zynq UltraScale+ IC and measures 60 x 42 x 11mm. The kit, called KD240 drives starter kit, includes the module, a carrier card and a heat sink. Included is 2Gbyte (2chan x 256Mbit x 16bit/chan) of LPDDR4, and a 512Mbit QSPI ...

That long-awaited Raspbrerry Pi Pico CNC control board has emerged

PicoCNC Raspberry Pi Pico CNC control board PhilBarret Brookwood GitHub

PicoCNC, the Raspbrerry Pi Pico based CNC control board, has finally emerged from development by Phil Barrett of Brookwood Design, which has a web store on Tindie. First mooted by publicly by him in April 2021, all went quiet in the grblHAL GitHub discussion that August, until now, two years later. And the result looks very nice (and they seem ...

One I missed: led driver repurposed for 16 servos

NXP PCA9685 I2C pwm IC

I was looking at the electronics behind the little Petoi dog robot (right), and noticed a chip I was not aware of before, NXP’s PCA9685. On a deeper delve, I noticed Adafruit also uses it for creating the classic 1.0 – 2.0ms pulses that tell hobby servos where to position. It has an I2C input, and can create up to ...

Automotive motor drivers have Cortex-M3 and CAN-FD

Infineon TLE989x motor driver app

Infineon Technologies is aiming at automotive motors with driver ICs that combines gate drivers, a 60MHz Arm Cortex-M3 microcontroller, a 2Mbit/s CAN (FD) interface, a UART with LIN support, and motor current and voltage sensing. TLE988x are two-phase (H-bridge) devices TLE989x are three-phase devices “The ICs are AEC Q-100 qualified, making them ideal for automotive brushed dc and brushless dc ...

Toshiba second-sources four 50V motor drivers

Toshiba TB67S581 motor driver

Toshiba has introduced four 50V motor drive ICs that are “drop-in compatible with popular devices”, it said. The technology is BiCD, with Dmosfet output transistors. TB67S581FNG (2.5A output) and the TB67S580FNG (1.6A output) are two-phase bipolar stepping motor drivers. TB67H481FNG (PWM input) and TB67H480FNG (phase-enable inputs) are constant-current (up to 2.5A) dual H-bridge drivers for dc brushed motors or bipolar ...

Renesas and Nidec put inverter, on-board charger, and more, into vehicle motor-gearbox

Nidec 2018 e-axle

Renesas Electronics has teamed up with electric motor maker Nidec to develop a 6-in-1 e-axle for electric vehicles. E-axles combine motor, inverter and gearbox into one unit and, according to Renesas, are beginning to collect other power electronics functions such as dc-dc converters and on-board chargers to form a convenient package for car makers to integrate – an idea dubbed ...
