STMicroelectronics’ 650V IGBTs Boost Performance
The STMicroelectronics HB2 650V IGBT series delivers efficiency and performance gains for medium- and high-speed applications such as PFC converters, welders, uninterruptible power supplies (UPS), and solar inverters, leveraging ST’s latest Trench Field Stop (TFS) technology. The series also includes automotive-eligible devices meeting AEC-Q101 Rev. D. Joining the STPOWER portfolio, the new HB2 series has outstanding conduction performance thanks to low VCEsat of 1.55V. At the same time, dynamic behaviour is enhanced due to reduced gate charge that enables fast switching at low gate current. Outstanding thermal performance helps maximize reliability and power density, while the new products are also positioned as a very competitive choice in the market.
The HB2 series IGBTs can be specified with either a full-rated or half-rated diode, or a protection diode to prevent accidental reverse bias, giving extra freedom to optimize the behavior for specific application needs. This package is designed for use in space-constrained applications power conservation is critical.
The LIS2D2DTW12 has four user-selectable full acceleration measuring scales: ±2g/±4g/±8g/±16g. 16-bit output rates can range from 1.6 Hz to 1600 Hz. There are a total of 65 user modes that enable designers to control the unit’s power consumption.
It is configured to detect if the device it’s built into is in portrait or landscape orientation (4D orientation). It also has 6D orientation capability, which provides more detailed information about the device’s spatial position.
The unit offers configurable recognition between single-taps and double-taps. It can also detect freefall and motion used to tell the device when to “wakeup” from a sleeping/low power mode.
Temperature sensing is accomplished with output data rates (ODRs) ranging from 50 to 1.6 Hz and resolution from 8 to 12 bits.
To enhance the overall speed of system operation, the unit has an integrated 32-level first-in, first-out (FIFO) buffer. This allows the LIS2D2DTW12 to store data internally in order to limit intervention by the host processor.
Communication is accomplished through an SPI (Serial Peripheral Interface) or an I2C (inter-integrated circuit) interface.
The first of the new 650V devices, the 40A STGWA40HP65FB2, is available now in the TO-247 long-lead package, priced from $2.95 for orders of 1000 pieces.
