1 kW engine cooling fan reference design powered by 12V vehicle battery
The reference design is an automotive 3-phase motor drive for engine cooling fan application using MOSFETs with a gatecharge > 100nC presents the current capability via the first worldwide integrated bridge driver capable to drive 1kW motors at 12V. The main components used in the reference are:
- TLE9879QXW40: This device is a part of Embedded Power IC family and it is a single chip 3-phase motor driver, System-on-Chip (SoC) solution. It integrates an industry standard Arm® Cortex®-M3 core along with LIN transceiver, bridge driver and power supply, enabling the implementation of advanced motor control algorithms such as sensorless field-oriented control (FOC).
- IAUA250N04S6N007: This is an OptiMOS™-6 40 V MOSFET in high-power leadless sTOLL package, providing higher current capability in smaller form factor of 7x8 mm² without sacrificing thermal performance. In combination with OptiMOS™-6 40 V power MOS technology, sTOLL offers best in class power density and power efficiency at Infineon’s well known quality level for robust automotive packages.
The reference design is optimized in terms of EMC and thermal behaviour. Moreover, it includes comprehensive support material including layout and schematic files (Altium), EMC tests, thermal analysis and detailed documentation.
