Melexis rolls out 600mA single coil fan driver IC

Melexis has launched a 600mA single coil fan driver IC that claims to ease the development of energy efficient cooling system designs. The MLX90297 is part of the company's portfolio of All-In-One single coil fan drivers and integrates a high sensitivity Hall Effect sensor with two powerful half bridge output stages, indicated the company.


In addition to the minimum speed setting incorporated into the MLX90287, the speed curve of MLX90297 can also be tuned through inclusion of just one extra resistor. The soft start and soft switching mechanisms have been further refined to achieve industry-leading acoustic noise levels, as well as low vibration at higher speeds, without maximum motor torque being sacrificed.

The reduced driver resistance (RDSon) of the MLX90297, in combination with the built-in current limiting, allows application of this fan driver to fans with coil resistances substantially lower than 10Ω. The electrostatic discharge (ESD) performance has been further enhanced to achieve 9kV HBM. The device is offered in a straight lead SOIC8 package. A DFN10 3mm x 3mm exposed pad package option is also available for very small fans and fans with motor currents up to 600mA.

"Our All-In-One MLX90287 in straight lead SOIC8 product has been received very warmly by the fan driver market. It lowers the total BOM cost and the complexity of the PCB design significantly by reducing the number of discrete components involved. Previously up to 22 resistors and transistors might have been needed for a TSSOP16 fan driver with an external hall sensor. Now just two resistors, and one decoupling capacitor are required for a SOIC8 fan driver solution," noted Dirk Leman, product line manager for fan drivers at Melexis.
