Product details
Overview
IRDM982-025MB from Infineon is a complete 3-phase PM motor controller module integrating six 500V/2A power MOSFETs, high-voltage gate drivers, Hall sensor interface, 3.3V regulator, and ROM-stored quadratic phase advance control algorithm for sinusoidal fan motor operation. It operates from a single 15V supply, requires no external heatsink, and delivers dynamic overcurrent, overspeed, rotor lock, and overtemperature protection in a 12×12 mm² PQFN package.
For engineers reviewing the IRDM982-025MB datasheet, IRDM982-025MB pinout, IRDM982-025MB application, or IRDM982-025MB equivalent, this module enables rapid deployment of brushless DC fan control without firmware development-selection of one of 16 pre-stored load curves is done via two resistor pairs on EFF pins, and direction is set via DIR input.
Technical Context
The IRDM982-025MB implements a Hall-sensor-based commutation scheme for 3-phase permanent magnet motors, using internal ADC sampling of VSP (speed reference), temperature, and EFF (load curve selection) to dynamically adjust phase advance per motor load. Its digital control block executes a fixed quadratic phase advance algorithm stored in ROM-no programming required.
It integrates a 600V high-voltage IC with full three-phase gate drivers, bootstrap FETs emulating diodes, and dual-regulated outputs: 15V for analog/driver circuitry and 3.3V for digital logic and Hall sensors. Clock generation uses an external RC network on CLKIN/XTAL pins, supporting 32.768 kHz reference or RC-derived timing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase PM fan motor control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRDM982-035MB | Same control architecture and package, but uses 500V/3A MOSFETs for higher current capability | Suitable for fans requiring >2A peak phase current or higher torque at low speed | Select when motor RMS current exceeds 1.4A or thermal margin is constrained by ambient >70°C |
| STSPIN32F0B | 32-bit ARM Cortex-M0 MCU + gate drivers; requires firmware development and external MOSFETs | Offers field-oriented control (FOC), but adds BOM complexity and validation effort | Choose only if advanced diagnostics, communication (UART/SPI), or custom torque profiles are mandatory |
Compared with IRDM982-035MB, the -025MB trades peak current headroom for tighter thermal footprint; versus STSPIN32F0B, it delivers faster time-to-market and lower system cost by eliminating MCU programming, external MOSFETs, and discrete protection components.

FAQ
What is the maximum continuous phase current supported by IRDM982-025MB?
The IRDM982-025MB integrates six 500V/2A MOSFETs rated for 2A continuous drain current each. Under typical PCB thermal conditions (2-layer 2 oz Cu, 10 cm² copper pour), it supports up to 1.4A RMS phase current with ≤70°C case temperature rise. Derating is required above 60°C ambient or with reduced copper area.
Can IRDM982-025MB operate without external Hall sensors?
No-IRDM982-025MB requires three differential Hall sensor inputs (HALL1+/− through HALL3+/−) for rotor position feedback. It does not support sensorless back-EMF commutation. The device expects standard bipolar latching Hall sensors powered by its internal 3.3V regulator.
How is motor direction controlled?
Motor direction is set via the DIR pin: logic high selects clockwise (CW) rotation, logic low selects counterclockwise (CCW). This is a static digital input sampled at startup and during direction-change transitions; no PWM or timing constraints apply beyond standard CMOS level compatibility.
Does IRDM982-025MB require an external crystal?
No external crystal is required. The device supports clock generation via an external RC network connected between CLKIN and XTAL pins, or optionally accepts a 32.768 kHz crystal. The RC solution reduces BOM cost and board space while meeting timing accuracy requirements for fan-speed control.
