Melexis, a global microelectronics engineering company, recently introduced the MLX90412-L as the automotive variant of its 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 2.2 A. It’s suitable for air pumps, water pumps, axial fans, as well as radial and cross blower applications.
Operating on a voltage ranging from 3.5 to 32 V, and reliable up to 40 V, the MLX90412 is well suited for any fan, blower, or pump applications operating on 12 V (automotive) and 24 V (trucks) board nets. It’s also ideal for driving loads from 0.1 W up to 20 W.
The MLX90412-L is AECQ100 certified. It can be applied on the automotive battery without additional protection and survives load dump pulses up to 40 V. The operating junction temperature ranges from -40° to 150° C. Typical applications include seat blower fans, battery cooling fans, 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 that were previously considered exclusive to more costly three-phase solutions. The MLX90412-L comes in a small Exposed pad DFN10 3×3 and is available for order now.
