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

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 fuel pumps. 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.

Supporting the trend away from relay-based to MOSFET-driven solutions, Infineon offers a family of integrated solutions: Half Bridge Driver ICs. This product family is designed to offer highly integrated cost-optimized motor control solutions for smart DC brushed motor control applications can be addressed either with a PN or NN MOSFET. Especially HVAC blowers, single-phase auxiliary pumps and fans´ requirements fit perfectly with our Half-Bridge Driver IC family. These System-on-Chip solutions enable a system solution that increases efficiency using smart power-on-demand control. The TLE9845QX and TLE9851QXW enable a true mechatronic solution that places the electronics adjacent to the motor. As a result, the external control signal (LIN or simple PWM) to the motor controller does not produce any unacceptable emissions that can disturb other electronic components in the car. Additionally, 32-bit core for complex software solutions with Direct Memory Access (DMA) Controller up to 14 channels ensure high performance for applications.
