Infineon TLE 986 User Manual

Product Brief

The TLE986x family is part of the Infineon Embedded Power IC portfolio. The TLE986x is a single chip 2-phase motor driver that integrates the industry standard Arm® Cortex®-M3 core, enabling the implementation of advanced motor control algorithms. It includes four fully integrated NFET drivers optimized to drive a 2-phase motor via four 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 TLE986x family offers 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.

It is a highly integrated automotive (grade-1 & grade-0) qualified device enabling cost and space efficient solutions for mechatronic DC motor drive applications such as sunroof, power window lifts, exhaust flaps and water valves lift.

Key benefits

› Enable cost and board space improvements – Our system-on-chip solution for DC

motor control integrates data processing, actuation and sensing. The chip comes in a leadless VQFN package with 7x7 mm footprint and enables PCB space saving. The TLE986x family allows driving MOSFETs at V

BATT

≥ 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 TLE986x

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.
