High efficiency control by quadratic phase advance curve
Internal clock based on external RC
15V single power supply
3.3V Integrated Voltage Regulator
Integrated protection features:
Dynamic overcurrent , Overtemperature ,
Overspeed, Rotor lock, Undervoltage lockout
Full Three Phase Gate Driver
Integrated Bootstrap Diodes
No heatsink required
12x12 mm² PQFN package
Applications
PM fan motor control
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

Introduction
IRDM983-025MB, IRDM983-035MB are the complete PM motor controller including six power
MOSFET, high voltage integrated circuit, high precision analog circuit and digital control
algorithm. There are two products depending on power rating of internal high voltage MOSFET
listed below:
1) IRDM983-025MB – employs six MOSFET 500V 2A and 600V high voltage IC
2) IRDM983-035MB – employs six MOSFET 500V 3A and 600V high voltage IC
All two products are packaged in the 12 x 12 PQFN package and designed to dissipate the power
loss through a mating PCB without an external heatsink. All two products contain exactly same
control algorithm and analog functions. The controller implements a two Hall sensors based
control algorithm for 3-phase sinusoidal permanent magnet motor fan applications. The control
also employs high efficiency PM motor control algorithm based on a quadratic load curve stored
in internal ROM. 16 possible curves are selectable.
All devices have an on-chip voltage regulator to derive the 3.3V, required by the digital logic, from
the 15V (VCC) supply. The 3.3VDC regulated voltage pin is available externally for connection to
Hall-effect sensors. The IC provides low power standby (less than 7mW) mode of operation that
3.3V power is cut off when VSP (Voltage Input) becomes less than 1.15V to provide further power
efficient operation.
An integrated A/D Converter is used to acquire EFF load curve selection, temperature (internal
temp sensing), and the VSP input that sets the voltage applied to the motor.
An internal temperature sensor is interfaced to the ADC and resulting digital conversion data is
used to control the dynamic overcurrent setpoints as well as max overtemperature limit.
The protection functions include a supply under-voltage lockout (3.3V and 15VDC), over-speed
protection, over-temperature limit and Over-current limitation protections. The reset circuitry
includes a Power-On reset block and a reset input.
All devices do not require any programming. Default coefficients and system parameters are
stored in internal ROM. The EFF input pin, used to adapt to specific motor and load to improve
efficiency, can be used by means of two resistor pairs to choose one of 16 pre-stored load curves
in ROM. DIR is a digital input pins which specify the motor direction command (CW or CCW).
All devices have an on-chip PLL to generate internal clocks. The PLL requires an external low
frequency reference clock (32,768 Hz). The clock can be provided through an RC network
connected to CLKIN and XTAL pins.
The IRDM983-025MB, IRDM983-035MB integrate high and low side gate drivers for applications
up to 500V, it includes integrated Bootstrap FET that emulate bootstrap diode function and six
power MOSFETs. The simplified block diagram is shown in Figure 1 in terms of hardware
elements.
