IRDM982 Series
Introduction
IRDM982-025MB, IRDM982-035MB are the complete PM motor controller including six power
MOSFET, high voltage integrated circuit, high precision analog circuit and digital control
algorithm. There are three products depending on power rating of internal high voltage MOSFET
listed below:
1) IRDM982-025MB – employs six MOSFET 500V 2A and 600V high voltage IC
2) IRDM982-035MB – 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 Hall sensor 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 IRDM982-025MB, IRDM982-035MB 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.

Recommended Operating Conditions
For proper operation, the device should be used within the recommended conditions. All voltage parameters are absolute
voltages referenced to VSS unless otherwise stated in the table.
The input/output logic timing diagram is shown in Fig. 1.
The VS and VSS offset rating are tested with all supplies biased at a 15 V (VCC) differential / 3.3V (VDD).
Power up and down sequences are not dependent on the order of VCC, DCBUS, and VSP for proper operation to start or
stop.

Load Curves
The following Table shows EFF pin mapping between input voltage and the advanced angle in degree per
50Hz of fundamental electrical frequency. Phase advance is by design clamped to be lower than 45 degrees
at every frequency. At frequencies above 100 Hz the advancement is constant and it is kept to the same
value at 100Hz.
