Engine and battery cooling fan

The engine/battery cooling fan is one of the main thermal management components in the engine compartment. The move to improve fuel efficiency and reduce emission levels is placing the spotlight on alternative power solutions such as 48 V battery systems. Delivering the same power as 12 V and 24 V systems, 48 V technology lightens the 12/24 V board net workload. At the same time, it substantially reduces the current and, as such, the weight of cables and motor windings. Infineon’s 3-phase gate driver ICs are suited to all three voltage classes.

Low integration level: 3-phase gate driver IC for 12 V, 24 V and 48 V battery systems

A low level of integration based on discrete components gives you the flexibility to select the optimal device for each function. The result is a tailor-made design that fits your target application like a glove. High-current drives in particular benefit from the latest MOSFETs offering lowest RDS(on) in thermally optimized packages.

Infineon’s advanced gate driver ICs (e.g. TLE9180D-31QK) are capable of controlling 6 external N-channel MOSFETs, thus forming an inverter for high-current 3-phase automotive motor drives. The sophisticated high-voltage technology in these ICs supports single and mixed battery applications with voltages from 12 V to 48 V.
