Stepper drivers self-tune motor parameters for life

There is no need to manually tune stepper motor drives, claimed Texas Instruments, as it introduced two 24V stepper motor driver chips with its patented ‘AutoTune’ technology. “AutoTune technology on the DRV8880 and DRV8881 eliminates the iterative process of manual tuning,” said TI. “On-chip intelligence dynamically monitors the motor’s performance under varied conditions over its life-time and adjusts ...

Power Integrations ac-dc converter delivers constant power

Power Integrations has developed a version of its InnoSwitch family of off-line power converter chips for constant power outputs. Called Innoswitch-CP, the converters are CV/CC fly-back switching ICs, that unsusually have a constant power output limit which, “when paired with an adaptive-voltage protocol such as Qualcomm Quick Charge 3.0 or USB-PD, permits smart mobile device ...

Vishay aims at notebooks with mosfet power stages

Vishay has introduced 30 and 40A mosfet power stages in 4.5×3.5 and 5x5mm packages respectively. Intended for notebook PCs, they accept PWM inputs and combine switching mosfets, gate drivers and a bootstrap Schottky diode. On-board high and low-side mosfets are GenIV TrenchFETs, the driver IC is supports 5V tri-state PWM logic, and 45 % footprint saving is claimed over discrete solutions. ...

Predictions 2016: contact technology will change connectors

Electroforming contacts is better than stamping and pressing when manufacturing miniature connectors, writes Hafeez Najumudeen Whilst semiconductor manufacturers have been halving the size of transistors roughly every two years, connector manufacturers have been a long way from keeping pace. One of the reasons is there has been no fundamental change in contact manufacturing techniques. Electroforming ...

Predictions 2016: datacentres get 100Gbit/s optical links, says Imec

If we want to make silicon photonics technology cost-effective, we have to optimize the packaging, writes Joris Van Campenhout, Imec programme director for optical I/O. Optical data transmission is a key answer to the ever growing data traffic. Today, data centres make use of hundreds of thousands optical links that interconnect the server racks at ...
