Product details
Overview
IRDM982-035MBTR from Infineon is a fully integrated 3-phase permanent magnet motor controller module with six 500V/3A power MOSFETs, Hall-sensor-based sinusoidal commutation, quadratic phase advance control, 15V single-supply operation, and integrated 3.3V regulator - designed for industrial PM AC fan systems requiring compact, heatsink-free motor drive solutions.
For engineers reviewing the IRDM982-035MBTR datasheet, IRDM982-035MBTR pinout, IRDM982-035MBTR application, or IRDM982-035MBTR equivalent, this page delivers verified technical context, validated pin functions, confirmed protection features (dynamic overcurrent, overspeed, rotor lock), real-world application cards, and two rigorously cross-checked alternative parts with documented functional differences.
Technical Context
The IRDM982-035MBTR integrates a digital motion controller with fixed ROM-stored algorithms for Hall-based 3-phase sinusoidal commutation, supporting selectable 4 or 12 pulses per mechanical revolution (with 8-pole motors). It uses an internal PLL clock synthesized from an external 32.768 kHz RC network on CLKIN/XTAL pins.
It implements dynamic overcurrent limiting tied to internal temperature sensing via integrated ADC, plus undervoltage lockout on both 15V (VCC) and 3.3V (VDD) rails, rotor lock detection, and overspeed protection - all without firmware programming or external microcontroller coordination.

Pinout & Package
IRDM982-035MBTR is housed in a thermally enhanced 12 mm × 12 mm PQFN package with exposed thermal pad (pin 1–24 layout per datasheet Figure 2 and Lead Definitions section). The package supports direct PCB copper pour thermal coupling and eliminates need for external heatsink.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | 15V main supply input | Primary power rail for HV IC and gate drivers; UVLO threshold at 12.5V |
| VSS | Ground reference | Common return for analog/digital/HV sections; requires low-impedance PCB connection |
| HALL1+/HALL1− | Hall sensor differential input | Accepts open-collector Hall signals; supports 3-wire Hall sensors with internal bias |
| DIR | Digital direction command | Active-high logic input selects CW/CCW rotation; level-triggered, no debouncing required |
| VSP | Speed setpoint analog input | 0–15V input scaled internally to define motor voltage output; enables closed-loop speed tuning |
| EFF | Efficiency curve selection | Resistor-divider input selecting one of 16 ROM-stored quadratic load curves for optimal torque/speed matching |
| U/V/W | Phase outputs | High-side and low-side driver outputs connected directly to motor windings; rated for 500V blocking |
| VBUS | DC bus input | High-voltage DC link connection (≤500V); feeds internal bootstrap circuitry and gate drivers |
Key Features
| Feature | Design Value |
|---|---|

| Heatsink-free thermal design | 12×12 mm PQFN package transfers heat directly to PCB copper area; validated for continuous 3A RMS motor current without heatsink |
| Dynamic overcurrent protection | ADC-monitored internal temperature adjusts overcurrent trip threshold in real time - prevents false trips during transient thermal events |
| Integrated bootstrap diodes | On-chip FETs emulate bootstrap diode function - removes need for external discrete diodes and reduces BOM count and layout area |
| Low-power standby mode | Automatic 3.3V rail shutdown when VSP falls below 1.15V - reduces system idle power to <7 mW |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase PM motor controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRDM982-025MBTR | Same IC core and algorithm, but uses six 500V/2A MOSFETs instead of 3A; lower continuous current rating | Suitable for ≤150W fan loads vs. 200W+ for -035MBTR; identical pinout and control interface | Select when motor RMS current stays below 2A and thermal margin allows smaller PCB copper area |
| STSPIN32F0B | ARM Cortex-M0-based programmable driver; requires external MOSFETs; no integrated power stage | Supports field-oriented control (FOC) and custom tuning; lacks integrated overtemperature/overspeed hardware protection | Choose when advanced control (e.g., sensorless startup, adaptive load compensation) is required and external MOSFETs are acceptable |
Compared with IRDM982-025MBTR, the -035MBTR delivers higher continuous motor current (3A vs. 2A) and greater thermal headroom; versus STSPIN32F0B, it trades programmability for plug-and-play robustness, integrated power, and hardware-enforced safety protections.

FAQ
What is the maximum continuous motor current supported by IRDM982-035MBTR?
The IRDM982-035MBTR integrates six 500V/3A MOSFETs and is rated for continuous RMS motor current up to 3A under standard PCB thermal conditions (≥200 mm² 2-oz copper pour per phase). Derating applies above 70°C ambient or with reduced copper area.
Does IRDM982-035MBTR require external programming or configuration?
No. The device contains 16 pre-stored quadratic load curves and fixed Hall-based commutation firmware in ROM. Configuration is done solely via passive components: two resistor pairs on EFF and PGSEL pins select load curve and pulse mode - no JTAG, UART, or flash programming is needed or supported.
Can IRDM982-035MBTR operate without an external crystal or oscillator?
Yes. It uses an internal PLL clock generator that accepts an external RC network (not a crystal) connected between CLKIN and XTAL pins. A 32.768 kHz RC oscillator is sufficient; no crystal or external clock source is required.
What thermal management is required for IRDM982-035MBTR in continuous operation?
The 12×12 mm PQFN package is designed for PCB-only thermal dissipation. A minimum of 200 mm² of 2-ounce copper connected to the exposed thermal pad is required. No heatsink, thermal paste, or forced airflow is necessary for rated 3A RMS operation at ≤70°C ambient.
