TLE984x Infineon® Embedded Power IC

Relay Driver IC with integrated ARM® Cortex™-M0 MCU

The TLE984x product family integrates an ARM® Cortex™-M0 microcontroller core along with relay drivers, high-side switches, LIN transceiver, and a power supply system that enables the device to operate at the vehicle battery level.

Its peripheral set includes a 10-bit ADC with 13 multiplexed analog inputs to process up to 5 high voltage monitoring inputs, 6 low voltage inputs, and 2 high voltage inputs for sensing the battery voltage and the supply of the device. It further includes an 8-bit ADC with 7 multiplexed inputs for voltage and temperature supervision. Its digital peripherals include a PWM signal generator unit and 16-bit timers along with a number of general purpose I/Os (Serial Interfaces and UARTs). It includes an on-chip linear voltage regulator to supply external loads.

The TLE984x family concept offers scalability in terms of Flash memory sizes ranging from 36 kB to 64 kB with pin-compatible devices. It is specifically designed to drive a wide range of LIN-slave motor control automotive applications via a relay or via a PN MOSFET Half-Bridge, such as window lifts, sunroofs, wipers, electric fans, and pumps, to name a few.

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 7 x 7 mm footprint and enables PCB space saving. The TLE984x family allows driving MOSFETS at VBATT ≥ 6 V without external components, providing a very cost effective solution on a system level.
  • Enabling 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, both the Embedded Power IC and the external MOFESTS can be protected.
  • Support multiple and flexible designs with minimal effort – All TLE984x devices are pin and software compatible, maximizing a single design through scalability.

TLE987x Infineon® Embedded Power IC

3-phase motor driver with integrated ARM® Cortex®-M3 MCU

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.

Applications

  • Fuel pump
  • HVAC blower
  • Engine cooling fan
  • Water pumps
  • High efficiency pumps and fans
  • Sensor-less and sensor-based BLDC motor applications controlled by the Local Interconnect Network (LIN) or PWM
