Product details
Overview
IRSM807-045MH from Infineon Technologies (formerly International Rectifier) is a 4A, 500V half-bridge intelligent power module integrating dual Trench FREDFETs, high-voltage gate drivers, and bootstrap circuitry in an isolated 32-lead PQFN (8×9 mm) package. It delivers sinusoidal or trapezoidal motor control for energy-efficient small-appliance fans and pumps without requiring external heat sinking.
For engineers reviewing the IRSM807-045MH datasheet, IRSM807-045MH pinout, IRSM807-045MH application, or IRSM807-045MH equivalent, this module supports 3.3V logic-compatible inputs, matched 0.9–1.5 µs propagation delays, 1500 VRMS isolation, 1.5 Ω RDS(on) at 25°C, and operates up to 20 kHz PWM carrier frequency in space-constrained motor drive designs.
Technical Context
This module implements a fully integrated half-bridge topology with independent high-side (VB/VS) and low-side (VCC/COM) supply domains. Its internal driver includes under-voltage lockout on both channels (8.9 V turn-on, 7.7 V turn-off), 300 ns built-in dead time, and 300 ns input filtering to suppress noise-induced switching errors.
The FREDFETs feature 500 V blocking capability, 209 mJ single-pulse avalanche energy, and diode forward voltage of 0.85 V at 2 A. Thermal resistance is 1.55 °C/W junction-to-case bottom, enabling conduction-cooled operation without heatsink at ≤4 A DC load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Rated Current | 4 A DC continuous at TC = 25°C - supports fan/pump motors with steady-state loads up to 120 W at 30 V RMS phase voltage |
| Blocking Voltage | 500 V - withstands DC bus transients in 230 VAC rectified systems with margin for line surges |
| RDS(on) | 1.5 Ω (typ) at 25°C - enables <1.2 W conduction loss per FET at 2 A, reducing thermal stress in sealed enclosures |
| Isolation Rating | 1500 VRMS (1 min) - meets reinforced insulation requirements for Class I appliances per IEC 60335 |
| Logic Interface | 3.3 V compatible, active-high HIN/LIN - interfaces directly with MCU GPIO without level-shifting in modern embedded controllers |
| Propagation Delay | 0.9–1.5 µs (matched across channels) - ensures precise timing alignment between high/low-side switching for clean commutation |
| PWM Frequency | Up to 20 kHz - suppresses audible noise in appliance motors while maintaining efficient gate drive efficiency |
Pinout & Package
IRSM807-045MH uses a thermally enhanced 32-lead PQFN package (8 mm × 9 mm × 0.9 mm), with exposed copper pad on bottom for direct PCB thermal coupling. The package provides galvanic isolation between power and logic domains, and integrates bootstrap capacitor connection points (VB/VS pins).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 7, 32 | COM | Low-side gate drive return and logic ground reference - must be connected to PCB ground plane with low-inductance path |
| 2 | VCC | 15 V gate drive supply for low-side driver and logic - decoupled locally with ≥10 µF ceramic + bulk capacitor |
| 3 | HIN | Active-high logic input for high-side FET - accepts 3.3 V CMOS levels; internally filtered against EMI |
| 5 | LIN | Active-high logic input for low-side FET - synchronized with HIN via internal dead-time generator |
| 8–10 | V− | Low-side source connection - ties to motor winding return; shares COM reference but carries high di/dt current |
| 11–19, 29–30 | VS | Phase output node - connects to motor winding center tap or U/V/W phase; serves as floating return for high-side bootstrap |
| 20–28 | V+ | DC bus positive input - rated for 400 V max operating voltage; requires low-ESR bulk capacitance near module |
| 31 | VB | High-side floating supply (+) - connects to bootstrap capacitor anode; supplies gate drive for upper FREDFET |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Bootstrap Functionality | Eliminates external bootstrap diode and capacitor routing; reduces BOM count and layout area by >30% in compact fan modules |
| Matched Propagation Delay | ≤0.6 µs channel-to-channel skew ensures symmetrical dead-time insertion and prevents shoot-through during commutation |
| Optimized dV/dt Control | Internal gate resistance tuning limits voltage slew rate to balance switching loss vs. EMI in unshielded appliance enclosures |
| Under-Voltage Lockout (UVLO) | Dual independent UVLO (7.7 V turn-on hysteresis) prevents partial FET enhancement and thermal runaway during brownout conditions |
| 3.3 V Logic Compatibility | Direct interface with ARM Cortex-M, ESP32, and PIC microcontrollers without level shifters-reducing component count and signal integrity risk |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge motor drive applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FAN7382MX | Standalone high-/low-side driver (no integrated FETs); requires external 500 V MOSFETs and discrete bootstrap network | Suitable for higher-current (>6 A) or custom topology designs where thermal management is handled separately | Select when design requires flexibility in FET selection or higher voltage derating margin beyond 500 V |
| FSB50550 | 5 A, 600 V IPM in larger 23-pin DIP package; includes NTC thermistor and enhanced thermal pad but no 3.3 V logic support | Better suited for industrial blowers with forced-air cooling and 5 V logic interfaces | Select when higher current headroom or integrated temperature monitoring is required, and board space permits larger footprint |
Compared with FAN7382MX and FSB50550, IRSM807-045MH uniquely combines 3.3 V logic compatibility, 8×9 mm footprint, and integrated bootstrap in a 500 V half-bridge-making it optimal for cost- and space-sensitive consumer appliance motor drives where rapid time-to-market is critical.

FAQ
Does IRSM807-045MH require an external bootstrap diode?
No. The module integrates internal bootstrap functionality with dedicated VB and VS pins, eliminating the need for an external bootstrap diode. A single 0.22 µF ceramic capacitor between VB and VS is sufficient for typical 20 kHz PWM operation with 4 A load current.
What is the maximum allowable DC bus voltage for continuous operation?
The recommended maximum DC bus voltage is 400 V, as specified in the Recommended Operating Conditions table. While the FREDFETs are rated for 500 V blocking, sustained operation above 400 V increases avalanche stress and reduces reliability margin in appliance-grade thermal environments.
Can IRSM807-045MH drive a three-phase motor directly?
No. IRSM807-045MH is a single half-bridge (one high-side + one low-side switch). Driving a three-phase BLDC motor requires three such modules or a three-phase IPM like IRSM836-045. This part controls one phase leg only.
Is solder reflow profile information available for the PQFN package?
Yes. The module complies with IPC/JEDEC J-STD-020D moisture sensitivity level 3 and supports standard lead-free reflow profiles with peak temperature ≤260°C for 30 seconds. The bottom-exposed thermal pad must be soldered with ≥80% coverage for thermal performance.
