Infineon Technologies IRAMS10UP60B-4

Overview

IRAMS10UP60B-4 from Infineon Technologies (formerly International Rectifier) is a fully isolated 3-phase IGBT inverter module with integrated gate drivers, bootstrap diodes, internal shunt resistor (33.3 mΩ), NTC thermistor, and protection circuitry - designed for AC motor drive in washing machines and refrigerators. It delivers 10 A RMS phase current at 600 V blocking voltage, supports 20 kHz PWM, and features under-voltage lockout, cross-conduction prevention, and short-circuit rated IGBTs.

For engineers reviewing the IRAMS10UP60B-4 datasheet, IRAMS10UP60B-4 pinout, IRAMS10UP60B-4 application in appliance motor control, or IRAMS10UP60B-4 equivalent for compact inverter design, this hybrid IC provides plug-and-play integration with single-polarity 15 V supply, matched propagation delay (<75 ns), and 2000 V_RMS isolation - critical for safety-certified white goods power stages.

Technical Context

The IRAMS10UP60B-4 integrates six IGBTs (three half-bridges), three high-side gate drivers with bootstrap diodes, logic-level inputs (Schmitt-triggered), and fault management via ITRIP and FLT/EN pins. Its internal shunt enables direct current sensing without external amplifiers, while the embedded NTC thermistor (R₂₅ = 100 kΩ, B = 4250 K) provides real-time die temperature monitoring.

Protection architecture includes undervoltage lockout on both VCC and VBx supplies (11.1 V threshold), blanking-timed overcurrent detection (150 ns ITRIP blanking), auto-reset fault recovery, and matched turn-on/turn-off delays to ensure precise dead-time control. The module operates across –40°C to +150°C junction temperature with R_th(J–C) = 4.2°C/W per IGBT.

FAQ

What is the maximum allowable case temperature for continuous 10 A RMS operation?

The IRAMS10UP60B-4 supports 10 A RMS phase current only when case temperature (T_C) is maintained at or below 25°C, as specified in the Absolute Maximum Ratings table. At T_C = 100°C, rated RMS current drops to 5 A due to thermal derating of IGBT conduction losses and safe operating area limits.

How does the internal shunt resistor interface with external current-sense amplifiers?

The 33.3 mΩ shunt connects between the phase output (e.g., U/VS1) and the negative DC bus (V−). Its differential voltage is accessed via dedicated ITRIP and COM pins; external amplifiers must be rail-to-rail input types with common-mode range covering –0.3 V to +15 V relative to COM, and bandwidth ≥1 MHz for accurate overcurrent detection.

Can the FLT/EN pin be used for both fault reporting and hardware enable control?

Yes - FLT/EN is a bidirectional open-drain pin. When driven low externally, it disables all six IGBTs immediately (hardware enable function). When released, it acts as an active-low fault flag: pulled low during overcurrent, overtemperature, or UVLO events, and returns high after auto-reset completes (typically within 10 ms after fault removal).

What is the recommended minimum creepage distance for PCB layout around the high-voltage pins?

The module's internal creepage is ≥3.2 mm, but PCB layout must maintain ≥4.0 mm creepage between V+, V−, VBx, and VSx pins and any low-voltage traces (e.g., HIN/LIN, VCC, VSS) to comply with IEC 60664-1 Pollution Degree 2 requirements. Solder mask is not considered insulation; slots or barriers may be required in high-humidity environments.
