Infineon has combined its wealth of experience in
motor control drivers for automotive applications with
an industry-standard core. The unique result, our 3
rd
generation embedded power IC based on ARM® Cortex®-M
cores, addresses a wide range of smart 2-phase DC motor
control applications like, sunroof, power window li,
electrical pumps, electrical fans.
Produced on Infineon’s first-in-industry automotive
qualified 130nm smart power technology, the Infineon
embedded power system-on-chip solutions oer
an unmatched level integration and system cost to
performance to optimization for the target application
segments.
The TLE986x family oers scalability in terms of flash
memory sizes and MCU system clock frequency supporting
a wide range of motor control algorithms. It uses the same
MCU and peripherals as the TLE987x family, 3-phase driver,
enabling design synergies between DC and BLDC motor
control applications
