Product details
Overview
98-0291 from Infineon Technologies is an intelligent power module (IPM) integrating six IGBTs, bootstrap diodes, gate drivers, and protection circuitry in a single 23-pin DIP-23 package. It supports 600 V/15 A three-phase motor drive applications with integrated overcurrent, overtemperature, and undervoltage lockout. Designed for HVAC compressors and industrial fans.
For engineers reviewing the 98-0291 datasheet, 98-0291 pinout, 98-0291 application, or 98-0291 equivalent, key selection criteria include integrated fault reporting via FO pin, 1500 Vrms reinforced isolation rating, and compatibility with 3.3 V / 5 V logic-level PWM inputs.
Technical Context
The 98-0291 implements a fully integrated three-phase inverter stage with monolithic gate drivers and analog current sensing. Its built-in thermal shutdown activates at 150 °C junction temperature, and the FO (Fault Output) pin provides open-drain active-low fault signaling synchronized to PWM cycle.
It uses high-side floating channel technology for bootstrap gate driving, supports dead-time insertion externally via input logic, and features under-voltage lockout thresholds of 12.5 V (VCC) and 9.5 V (VBS) with hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Voltage Rating | 600 V - withstands DC bus voltage up to 600 V in inverter topologies |
| Continuous Current | 15 A - rated RMS output current per phase at Tc = 80 °C |
| Isolation Rating | 1500 Vrms - reinforced isolation between power and control sides per UL 1577 |
| Logic Input Voltage | 3.3 V / 5 V compatible - accepts standard microcontroller PWM outputs without level shifting |
| Fault Output | Open-drain FO pin - signals overcurrent, overtemperature, or UVLO with cycle-by-cycle latch-off |
| Thermal Shutdown | 150 °C - internal sensor disables all IGBTs and asserts FO until reset |
Pinout & Package
98-0291 is housed in a 23-pin dual-in-line plastic package (DIP-23) with creepage/clearance optimized for industrial motor drives. Pin layout includes three high-side and three low-side gate driver inputs, three phase outputs (U/V/W), bootstrap supply pins (VB1–VB3), power rails (VCC, VBS, P, N), and dedicated fault reporting (FO) and enable (EN) terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| U, V, W | Phase Outputs | High-current terminals connecting to motor windings; rated for 15 A RMS each |
| P, N | DC Bus Inputs | Positive and negative terminals for 600 V DC link connection |
| HIN1–HIN3 | High-Side Inputs | 3.3 V / 5 V logic-level PWM inputs for upper IGBTs; internally level-shifted |
| LIN1–LIN3 | Low-Side Inputs | Direct logic-level PWM inputs for lower IGBTs; no level shift required |
| FO | Fault Output | Active-low open-drain signal indicating overcurrent, overtemperature, or UVLO |
| EN | Enable Input | Active-high logic input enabling/disabling all gate drivers globally |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Bootstrap Diodes | Eliminates need for external bootstrap diodes and reduces PCB component count by ≥6 parts |
| Analog Current Sense | Provides proportional voltage output (0.5 V/A) for real-time phase current monitoring |
| Reinforced Isolation | 1500 Vrms isolation enables direct MCU interface without optocouplers or isolated gate drivers |
| Cycle-by-Cycle Fault Latch | FO pin remains asserted until EN is toggled, preventing uncontrolled restart after fault |
Applications
| HVAC Compressor Drive | Industrial Fan Control |
|---|---|
Use Scenario: Variable-speed compressor in residential air conditioning units requiring EMI-compliant, compact inverter design. IC Role / Device Role / Timing Role: Three-phase inverter module delivering precise 0–20 kHz PWM-controlled motor torque and speed regulation. Use Value: Integrated protection eliminates external fault-detection circuitry and reduces BOM cost by ~12% versus discrete IGBT + driver solutions. | Use Scenario: Constant-torque fan in commercial building ventilation systems operating continuously at partial load. IC Role / Device Role / Timing Role: Intelligent power stage converting DC bus to variable-frequency AC for PMSM motor commutation. Use Value: Built-in thermal shutdown and FO reporting enable predictive maintenance alerts without adding temperature sensors or fault logic. |
| Pump Motor Inverter | Conveyor Belt Drive |
Use Scenario: 1–2 kW water circulation pump in smart building infrastructure with duty cycling and soft-start requirements. IC Role / Device Role / Timing Role: Power conversion module implementing space-vector PWM with programmable dead time via MCU. Use Value: Analog current sense output allows closed-loop current limiting during startup surge, reducing mechanical stress on impeller shaft. | Use Scenario: Low-speed, high-torque conveyor belt in packaging machinery requiring smooth acceleration/deceleration profiles. IC Role / Device Role / Timing Role: Motor drive stage supporting trapezoidal or sinusoidal commutation with integrated overcurrent response < 2 µs. Use Value: Sub-2 µs fault detection latency prevents IGBT short-circuit damage during jam events, improving system uptime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar intelligent power module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| FST412A (ON Semiconductor) | 600 V / 10 A rating; lacks analog current sense output; uses SO-24 package | Suitable only for lower-power fans (< 800 W); requires external current sensing | Select when cost sensitivity outweighs diagnostic capability and thermal margin |
| FSBB15CH60B (Fairchild/ON) | 600 V / 15 A; includes current sense but no FO pin; 25-pin DIP package | Requires external fault logic; less robust fault signaling than 98-0291's cycle-latched FO | Prefer where legacy board layout re-use is critical and fault reporting simplicity is secondary |
Compared with FST412A and FSBB15CH60B, the 98-0291 delivers superior system-level integration via its FO latch, analog current sense, and reinforced isolation-reducing external components and improving reliability in continuous-duty motor drives.

FAQ
What is the maximum allowable case temperature for continuous operation?
The 98-0291 is rated for continuous operation up to 100 °C case temperature (Tc) at full 15 A RMS load. Derating begins above this point, with thermal shutdown activating at 150 °C junction temperature. Thermal pad soldering to a 4-layer PCB with ≥20 cm² copper area is required to meet this spec.
Does the 98-0291 require external bootstrap capacitors?
Yes, external 0.1 µF ceramic bootstrap capacitors are required between each VBx and VSx pin. These must be placed within 5 mm of the module pins to ensure stable high-side gate drive under 20 kHz switching. No internal bootstrap capacitance is integrated.
Can the FO pin be used for real-time fault diagnostics?
Yes-the FO pin provides immediate, cycle-synchronized fault indication for overcurrent, overtemperature, and undervoltage conditions. Its open-drain output can directly interface with MCU GPIO interrupt pins, enabling sub-microsecond fault response without polling overhead.
Is the 98-0291 compliant with IEC 61800-5-1 for functional safety?
No-the 98-0291 is not certified to IEC 61800-5-1 or ISO 13849. It provides basic protection functions but lacks dual-channel monitoring, diagnostic coverage metrics, or FMEDA data required for SIL2/PLe safety-rated drives.
