Half-Bridge Driver IC with Integrated Arm® Cortex® M0
Infineon´s MOTIX™ 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. MOTIX™ 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. TheMOTIX™ 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 MOTIX™ Half Bridge Driver IC is pin-compatible to our MOTIX™ Relay Driver IC family and supports a platform approach. Therefore, it helps to reduce development time.
Infineon Developer Community is available 24x7 for you to connect and network with engineers across the globe. Get help from Infineon support engineers, and expert members to solve your design challenges anytime, from anywhere, in any topic, and in your preferred language.

- PCB sizing
- Compatible software reduces design costs and enables cost efficient PCB thermal design
QM-parts in Functional Safety Applications (ASIL)
Infineon`s MOTIX™ 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.
Together with our partners (Preferred Design Houses) we offer an optimized open market customer support for systems using our Embedded Power products. They are trained to provide application- and product-specific support.
