The TLE987x family is part of the Infineon Embedded Power IC portfolio. The
TLE987x is a single chip 3-phase motor driver that integrates the industry standard
Arm® Cortex®-M3 core, enabling the implementation of advanced motor control
algorithms such as field-oriented control. It includes six fully integrated NFET drivers
optimized to drive a 3-phase motor via six external power NFETs, a charge pump
enabling low voltage operation and programmable current along with current slope
control for optimized EMC behavior. Its peripheral set includes a current sensor, a
successive approximation ADC synchronized with the capture and compare unit for
PWM control and 16 bit timers. A LIN transceiver is also integrated to enable
communication to the device along with a number of general purpose I/Os. It
includes an on-chip linear voltage regulator to supply external loads.
The TLE987x family offers 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.
It is a highly integrated automotive (Grade-1 & Grade-0) qualified device enabling
cost and space efficient solutions for mechatronic BLDC motor drive applications
such as pumps and fans.
Key benefits
› Enable cost and board space improvements – Our system-on-chip solution
integrates data processing, actuation and sensing. The chip comes in a leadless
VQFN package with 7x7 mm footprint and enables PCB space saving.
The TLE987x family allows driving MOSFETs at VBATT ≥ 6V with a low number of
external components, providing a very cost effective solution on a system level.
Minimum number of external components reduces BOM cost.
› Support in-cabin and underhood applications with same design – some
TLE987x derivatives are qualified up to Tj= 175°C.and therefore enable a family
design approach due to pin, package and software-compatibility.
› Enable high levels of system reliability – Extensive diagnostics and protections
are embedded within the System-on-Chip, more than a discrete approach can
offer. In addition the Embedded Power IC and the external MOFESTs can be
protected.
