Infineon Technologies IRAMS10UP60B-2

Overview

IRAMS10UP60B-2 from Infineon Technologies (formerly International Rectifier) is a fully isolated 3-phase IGBT-based integrated power hybrid IC for appliance motor drives, featuring 600V blocking voltage, 10A RMS phase current rating at 25°C, internal 33.3 mΩ shunt resistor, integrated gate drivers with bootstrap diodes, and on-die NTC thermistor. It delivers fail-safe operation in washing machine and refrigerator inverter drives with built-in overcurrent, overtemperature, and undervoltage protection.

For engineers reviewing the IRAMS10UP60B-2 datasheet, IRAMS10UP60B-2 pinout, IRAMS10UP60B-2 application, or IRAMS10UP60B-2 equivalent, key selection criteria include its 2000 VRMS isolation rating, matched 590/700 ns propagation delays across all six channels, ±5% shunt tolerance, 440–540 mV ITRIP threshold, and UL E252584 recognition - critical for Class B insulation and safety-compliant white goods designs.

Technical Context

The IRAMS10UP60B-2 integrates three low V_CE(on) non-punch-through IGBTs with anti-parallel diodes, six high- and low-side gate drivers, bootstrap diodes, and a single 15V logic supply interface. Its driver core implements Schmitt-triggered inputs, cross-conduction prevention logic, and 220–360 ns programmable dead time to prevent shoot-through during PWM commutation.

Current sensing is implemented via an internal 33.3 mΩ shunt with 70–150 ns blanking time and 1.75 µs trip-to-shutdown propagation delay; thermal monitoring uses a factory-calibrated NTC (R₂₅ = 100 kΩ, B = 4250 K) connected to VTH. Protection functions include under-voltage lockout on VCC/VBS (11.1 V ±0.2 V), short-circuit safe operating area (10 µs @ 600 V), and RBSOA-rated IGBTs.

FAQ

What is the purpose of the VTH pin on IRAMS10UP60B-2?

The VTH pin connects directly to an internal NTC thermistor (R₂₅ = 100 kΩ, B = 4250 K) embedded in the IGBT die. It provides an analog voltage output that varies predictably with junction temperature, enabling real-time thermal monitoring and software-based derating. No external biasing or calibration is required - the thermistor is factory-trimmed and characterized across –40°C to +125°C.

Can IRAMS10UP60B-2 operate with a 12 V logic supply instead of 15 V?

Yes - the VCC absolute maximum rating is 20 V, and the recommended operating range is 12–20 V. At 12 V, gate drive strength remains sufficient for reliable IGBT turn-on (V_GE ≥ 12 V ensures full saturation), though propagation delays increase by ≤15% and UVLO thresholds shift proportionally. Designers must verify timing margins and short-circuit robustness under worst-case 12 V conditions.

How does the internal shunt resistor affect current measurement accuracy?

The 33.3 mΩ ±5% shunt enables current sensing with <±1% full-scale error at 10 A, assuming standard 1% external resistors in the ITRIP comparator circuit. Its low temperature coefficient (0–200 ppm/°C) minimizes drift across –40°C to +125°C. Accuracy is further enhanced by 100–150 ns blanking time, which suppresses switching noise during current-sense sampling.

What happens when FLT/EN is pulled low externally?

Pulling FLT/EN low disables all six gate drivers immediately - overriding active PWM signals and forcing all IGBTs into high-impedance off-state. This hardware emergency stop function is asynchronous and takes effect within one propagation delay (≤700 ns). The pin also reports faults: during overcurrent or overtemperature events, it sinks current through its 100 Ω on-resistance to signal the host MCU.
