The 2
nd
generation of Infineon® embedded power ICs
integrates on a single die all the necessary functions to
sense, control and actuate motor a via a relay or via a PN
MOSFET half-bridge. The TLE983x product family integrates
a high performance 8-bit microcontroller derived from the
established XC800 microcontroller family with application
specific power drivers, control and communication on
Infineon’s first-in-industry automotive qualified 130nm
smart power technology. TLE983x product family improves
the microcontroller performance and the product feature
set over the first generation (TLE78xx) product oering.
The TLE983x product family is oered in a space saving
PG-VQFN-48 package, while the first product generation
is realized as a Multi-Chip-Module (MCM) in a DSO-28
package.
The devices are designed for LIN based motor control
applications such as window lis, wipers, sun roofs, power
seats, fan/blower control.
