H-Bridge Driver IC with Integrated Arm® Cortex® M0

Overview

Infineon`s integrated motor driver optimizes the target applications by offering cost and energy effecient solutions

The TLE985x H-Bridge MOSFET driver IC product family is a compact and cost effective motor control solution. It targets automotive applications such as sunroof, window lift, gate lift and pumps.

It integrates the 32-bit Arm® Cortex®-M0 core together with market proven peripherals. It comprises two full duplex serial interfaces (UART) with LIN support, and two on-chip temperature and battery voltage measurement units.

Our highly integrated solution allows driving MOSFETs at low battery voltage (>=6V) with a minimum number of external components. This enables a very cost effective solution on a system level. Additionally, the TLE985x product family supports energy management and embeds several protection functions.

The TLE985x H-Bridge MOSFET driver IC has an adaptive control hardware implementation. The adaptive control algorithm is able to compensate the MOSFET parameters spread in the system. It is automatically adjusting gate current settings based on timing measurements to optimize the system`s EMC (slow slew rates) and power dissipation (short dead times).

QM-parts in Functional Safety Applications (ASIL)

Infineon`s Embedded Power ICs are developed as QM-parts, but nonetheless can be and are already used in a variety of motor control application that require Functional Safety (ISO26262) up to ASIL-B such as but not limited to Window Lift (ASIL-A), Sunroof (ASIL-A), Auxiliary pumps (ASIL-B) or Engine Cooling Fan (ASIL-B).

Infineon offers the following design-in support for its Embedded Power ICs:

  • FIT data information (ISO26262)
  • Function/Blocks vs. Area Breakdown

If these data is required, please contact your local Infineon partner who can provide you with these information.

How to use Keil µVision 5 Tool Chain for Infineon Embedded Power Boards

Infineon Embedded Power ICs`evalboards, evalkits and appkits are supported by a complete development tool chain. In this video, the tool chain is explained based on the example of our TLE9879 Evalkit. Either there is a stick which provides the development software in our kits or you can find the information either on the homepage or via the Toolbox. This stick includes compiler, debugger, documentation about toolchain setup and the user manual of the product, example codes, schematics of the evaluation kit and ConfigWizard. The last part of the video is a step-by-step guidance for setting up a program to test the blinking property of the LED lights on the board with Infineon’s System-on-Chip solution.
