Compact new IGBT modules save space in 250V area
Toshiba Electronics Europe has expanded its Compact Standard Series of IGBT modules with the addition of three new 250V devices aimed at high-power switching and motor control applications.
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
The new device accepts logic signals from the MPU or motor controller and will drive up to 2A through integrated IGBT outputs.
All necessary 3-phase decode logic, high-side and low-side drivers, FRDs (fast recovery diodes), over-current and under-voltage protection, and thermal shutdown circuitry are included in the TPD4104's 23-pin HZIP package.
This package has dimensions of just 31.5 x 16.1 x 5.1mm.
Built-in bootstrap diodes further simplify high-side design by eliminating external power supply hardware.
The TPD4104K is capable of handling voltages of up to 500V as a result of Toshiba's high voltage silicon on insulator (SOI) fabrication technology.
It accepts logic inputs between -0.5V to +7V, and also includes a built-in 7V regulator for the 3-phase decode circuitry.
Toshiba's new IC is rated up to 2A for continuous operation, or 3A under pulse load, and is suitable for operation from 240VAC mains and higher voltages.
As a result, the device is ideal for home appliances, industrial control systems, and other motor drive applications where short development time, small size and high reliability are primary design requirements.
