Melexis Announces an AECQ100 Certified 20W Single Coil Fan and Pump Driver for Automotive Applications
18 March 2021 - Melexis, a global microelectronics engineering company, introduces the MLX90412-L as the automotive variant of the already well established MLX90412.
The MLX90412-L is a dedicated automotive, all-in-one single-coil fan and pump driver IC, with a peak driving capability of 2.2A. It is suitable for air pumps, water pumps, axial fans and radial and cross blower applications. Operating on a voltage ranging from 3.5V to 32V, and robust up to 40V, the MLX90412 is well suited for any fan, blower or pump applications operating on 12V (automotive) and 24V (trucks) board nets. It is suitable for driving loads from 0.1W up to 20W.
The MLX90412-L is AECQ100 certified. It can be applied on the automotive battery without additional protection and survives load dump pulses up to 40V. The operating junction temperature ranges from -40℃ to 150℃. Typical applications include seat blower fans, battery cooling fan, DCDC converter cooling pumps or fans as well as HV inverter (IGBT/SIC cooling).
The MLX90412 offers unprecedented acoustic noise/vibration performance, making it a cost-effective alternative for applications which were previously considered exclusive to more expensive 3-phase solutions.
The MLX90412-L comes in a small Exposed pad DFN10 3×3 and is available for order.
