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 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, 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
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 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 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
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 ...
Oriental Motors introduces vector control for small dc brushless motors
Oriental Motors has introduced sinewave drive vector controllers for its 30 and 50W brushless dc motors, improving speed tracking, reducing audible noise, increasing peak torque (15% for 30W types and 20% for 50W) and adding functions compared with the earlier BLH series of squarewave controllers. The new controllers are called BLH2D (in photo right). “Adopting vector control as the motor ...
Embedded World: Harvesting NFC receiver for smart things
Infineon has created an IC to embedded in things that need to be controlled by a near-by mobile phone, which has in-built sensing and a motor driver. “Potential applications range from medical patches and disposable point-of-case testers, to data loggers, smart thermostats, smart locks and sensor inlays,” according to the company. Called NGC1081, the IC can be temporarily powered by ...
Automotive brushless dc motor driver supports ASIL-D
Toshiba has introduced a brushless dc motor driver that supports ASIL-D for functional safety in vehicles. Designed in accordance with ISO 26262 (2nd edition) and AEC-Q100-qualified, TB9083FTG is aimed at electric power steering, electric braking and shift-by-wire transmissions. “A built-in fail-safe safety relay pre-driver complements the three-phase pre-driver,” according to the company, and the “SPI communication interface features an integrated ...
