Infineon Technologies IRAMS10UP60A-2

Overview

IRAMS10UP60A-2 from Infineon Technologies (formerly International Rectifier) is a fully isolated 3-phase integrated power module for appliance motor drives, featuring six 600V IGBTs with matched propagation delay (470 ns turn-on, 615 ns turn-off), integrated gate drivers, bootstrap diodes, and built-in NTC thermistor for temperature monitoring. It delivers 10 A RMS phase current at 25°C, supports 20 kHz PWM carrier frequency, and provides overtemperature/overcurrent shutdown in washing machine and refrigerator inverter drives.

For engineers reviewing the IRAMS10UP60A-2 datasheet, IRAMS10UP60A-2 pinout, IRAMS10UP60A-2 application, or IRAMS10UP60A-2 equivalent, key selection criteria include isolation voltage (2000 V_RMS), R_th(J-C) of 4.2–4.7 °C/W per IGBT, T/ITRIP threshold (4.3 V), cross-conduction prevention logic, and low-side emitter pins (LE1–LE3) for shunt-based current sensing.

Technical Context

The IRAMS10UP60A-2 integrates three half-bridge stages with independent high-side (HIN1–3) and low-side (LIN1–3) logic inputs, each driving an IGBT/diode pair using IR21365-derived gate driver architecture. It employs non-punch-through IGBTs with V_CE(sat) = 2.0–2.4 V at 5 A and 25°C, and features Schmitt-triggered inputs with 3.0 V positive-going and 0.8 V negative-going thresholds.

Thermal protection is implemented via an internal 100 kΩ NTC thermistor (B = 4250 K) connected to the T/ITRIP pin, which triggers shutdown when voltage exceeds 4.3 V. Undervoltage lockout operates independently on VCC and VBx supplies, with hysteresis of 0.5 V and thresholds at 10.9–11.6 V.

FAQ

What is the maximum allowable DC bus voltage for IRAMS10UP60A-2?

The absolute maximum V₊ rating is 450 V, with V_CES = 600 V providing headroom for transients. Operation above 450 V violates recommended conditions and risks premature failure due to overstress on IGBTs and internal level shifters. Designers must ensure bus voltage remains within this limit under all load and line conditions, including regeneration events.

How is current sensing implemented using the LE pins?

The LE1–LE3 pins provide Kelvin connections to the low-side IGBT emitters, allowing direct placement of shunt resistors between LE and COM. This eliminates PCB trace resistance errors, enabling ±0.5% current measurement accuracy. The driver IC does not process this signal-it is routed externally to the MCU's ADC or dedicated current-sense amplifier.

Does IRAMS10UP60A-2 require external bootstrap capacitors?

No external bootstrap capacitors are needed-the module integrates ceramic capacitors internally for each high-side driver. However, a 1 µF low-ESR ceramic capacitor must be placed externally between each VBx pin and its corresponding VSx pin to stabilize the floating supply during switching transitions and prevent desaturation.

Can the T/ITRIP pin be used solely for overcurrent protection without thermistor connection?

Yes-the T/ITRIP pin accepts either the NTC voltage divider output or an external comparator signal. When used for overcurrent, a fast comparator (e.g., LM393) compares shunt voltage against a reference and pulls T/ITRIP low to trigger immediate shutdown (<750 ns propagation). The same pin cannot simultaneously serve both functions without external multiplexing.
