Half-Bridge Driver IC with Integrated Arm® Cortex® M0
Infineon´s Half Bridge Driver ICs are designed to provide energy and cost efficient solutions
With our single phase solution simple loads can be addressed either via PWM or LIN. To achieve a smallest in class footprint, Infineon provides a system-on-chip (SoC) solution built on 32-bit Arm® Cortex®-M0 core and offers a complete integration. TLE9845Qx is coming in a leadless VQFN package (7x7mm²) helping to save PCB space. This highly integrated product provides the capability to drive a power PN MOSFET Half-Bridge. The Half-Bridge is built up with a P-channel MOSFET in high-side and an N-channel MOSFET in low side position. The TLE9845Qx combined with the PN MOSFET half-bridge is designed to address smart DC brushed motor control applications like HVAC blowers or auxiliary pumps and fans. The system solution increases efficiency using smart power on demand control, and a true mechatronic solution that places the electronic at the motor. As a result, the external control signal (LIN or simple PWM) to the motor control does not produce any unacceptable emissions that can disturb other electronic components in the car.
Our Half Bridge Driver IC is pin-compatible to our Relay Driver IC family and supports a platform approach. Therefore, it helps to reduce development time.

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.
Infineon Embedded Power ICs are supported by a complete development tool chain provided by Infineon and third party vendors. The tool chain includes compilers, debuggers, evaluation boards, LIN low level drivers and configuration tools as well as variety of example software code.
For more information about the tool chain installation steps, watch our video "Toolchain Installation for Embedded Power ICs / TLE98xx".

Additional Tools for Design-in
Embedded Power ICs provide a built-in boot strap loader (BSL) for programming the system-on-chip devices over the built-in LIN transceiver or UART. The uIO Stick acts as an interface between the TLE98xx device and a PC. It handles the BSL protocols as well as the physical layers. A PC application (uIO BSL Tool) provides access to all BSL functions of the Embedded Power device.

The Micro Inspector (Pro) is a graphical visualization tool for embedded software based on Arm® Cortex®-M cores. It provides a simple & clean GUI where only relevant buttons & tabs are displayed. No programming knowledge is required. It provides a possibility to read & write the memory of embedded target processor during run time and offers a set of tool features (indicators & virtual controls) on graphical dashboards, which can be mapped to the memory locations.
-
Micro Inspector with a read-only view is free of charge and can be downloaded via the Infineon Toolbox.
-
Micro Inspector Pro offers the option to save your own dashboards. This version can be requested via our TAC and comes with a yearly fee of 399€/license.
