Description
IRDM983-025MB, IRDM983-035MB are the complete PM motor controller including six power MOSFET, high voltage
integrated circuit, high precision analog circuit and integrated digital control algorithm. The controller implements
a Hall sensor based control algorithm for 3-phase sinusoidal permanent magnet motor fan applications.
Other than the IRDM982 the IRDM983 only requires two hall sensors.
The integrated digital controller does not require any programming.
Instead there are 16 load curves stored in the internal ROM that can be selected via two resistor pairs.
The IRDM983 is packaged in the 12 x 12 PQFN package and designed to dissipate the power loss through a PCB
without the use of an external heatsink.
There are two products available depending on the power rating of the internal high voltage MOSFETs:
1) IRDM983-025MB – employs six MOSFETs 500V 2A and 600V high voltage IC
2) IRDM983-035MB – employs six MOSFETs 500V 3A and 600V high voltage IC
