Infineon has combined its wealth of experience in motor
control drivers for automotive applications with all
the benefits of 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
3-phase brushless DC motor control applications like,
fuel pumps, HVAC fans, engine cooling fans, electrical
water pumps. 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 TLE987x family oers scalability in terms of flash
memory sizes and MCU system clock frequency supporting
a wide range of motor control algorithms, either
sensor-based or sensor-less. It uses the same MCU and
peripherals as the TLE986x family, 2-phase driver, enabling
design synergies between DC and BLDC motor control
applications.
