Microcontroller meets needs of modern appliances
Toshiba Electronics Europe has launched a flash microcontroller specifically designed to meet the needs of modern home appliance applications including washing machines, dryers, and dishwashers.
First 7.7-inch low-temp polysilicon LCD for eBooks
Toshiba today announced commercialisation of a 7.7-in low-temperature polysilicon TFT LCD designed for mid-size electronic book devices incorporating Microsoft ClearType display technology
By combining sensorless operation with high levels of onboard functionality, the new ASSP will significantly reduce the component count, design complexity and development time of three-phase, full wave BLDC motor applications with power levels up to 60W.
In particular the device is ideal for home appliance, pump, industrial motion, automotive motor and other motion control applications requiring motor bridge voltages ranging from around 10 to 42V.
Toshiba's TB6588FG is a complete motor driver solution that controls forward or reverse rotation speed by changing the PWM duty cycle based on an analogue control signal input.
Full wave PWM operation provides for high-efficiency and low-power operation while minimising electrical and acoustic noise.
Lead angle control options of 0, 7.5, 15 and 30 degrees allow designers to tune their application for optimum efficiency.
The IC can deliver a maximum current output of 2.5A through its integrated power stage and offers configurable modes for improving the motor startup characteristic.
Built in protection against overcurrent conditions and the ability to enable detection of excessive commutation frequency and low rotation speed further improve design flexibility while minimising the need for external components.
