Infineon Technologies IRAMS12UP60A-2

Overview

IRAMS12UP60A-2 from Infineon Technologies (formerly International Rectifier) is a 12A, 600V integrated power hybrid IC with open-emitter pins, designed as a 3-phase inverter module for appliance motor drives. It integrates six Trench IGBTs, bootstrap diodes, high-voltage gate drivers, thermal monitoring via NTC thermistor, and protection logic including under-voltage lockout and over-current shutdown. Used in energy-efficient washing machine and refrigerator compressor drivers operating at 85–253 Vac.

For engineers reviewing the IRAMS12UP60A-2 datasheet, IRAMS12UP60A-2 pinout, IRAMS12UP60A-2 application, or IRAMS12UP60A-2 equivalent, key selection criteria include its 2000 VRMS isolation rating, matched 600 ns propagation delay across all channels, ±5% bootstrap resistor tolerance, 4.7 °C/W junction-to-case thermal resistance per IGBT, and integrated temperature-sensing NTC with R25 = 100 kΩ.

Technical Context

This HIC implements a fully isolated 3-phase inverter topology with independent high-side floating supplies (VB1–VB3) and open-emitter outputs (U/VS1, V/VS2, W/VS3), enabling direct connection to external current-sense shunts. The driver core uses Schmitt-triggered inputs, cross-conduction prevention logic, and internal 290 ns dead time to ensure safe commutation.

Protection architecture includes a dedicated T/ITRIP pin with 4.3 V threshold and 150 ns blanking time, short-circuit rated IGBTs (5 μs SCSOA), and undervoltage lockout on both VCC and VB supplies (11.1 V nominal trip). Thermal monitoring relies on an internal NTC thermistor (B = 4250 K, R25 = 100 kΩ) referenced to VSS.

FAQ

What is the purpose of the open-emitter pins (U/VS1, V/VS2, W/VS3) on IRAMS12UP60A-2?

These pins expose the emitter terminals of the high-side IGBTs, enabling Kelvin connection to external current-sense shunts. This configuration eliminates voltage drop errors caused by PCB trace resistance, allowing accurate phase current measurement essential for field-oriented control and overcurrent protection. Each pin is electrically isolated from the module baseplate.

How does the T/ITRIP pin function in dual-mode operation?

The T/ITRIP pin accepts either an analog voltage from the internal NTC thermistor (for temperature monitoring) or a digital overcurrent signal from an external comparator. Internal hysteresis (0.15 V) and 150 ns blanking prevent false triggering during PWM switching transients. When asserted, it forces all six IGBTs into immediate shutdown with 1.75 μs propagation delay.

Can IRAMS12UP60A-2 operate with a 400 V DC bus?

Yes - its 600 V VCES rating and 450 V maximum VS offset support reliable operation at 400 V DC bus. Derating is required above 100°C case temperature: RMS current drops from 12 A at TC = 25°C to 6 A at TC = 100°C per phase, as specified in Absolute Maximum Ratings.

What is the significance of CTI > 600 in the package specification?

CTI (Comparative Tracking Index) > 600 indicates exceptional resistance to surface tracking under humid, contaminated conditions. This allows the SIP package to maintain 8 mm creepage distance across the molded body without slotting or air gaps - critical for meeting IEC 60335-1 reinforced insulation requirements in household appliances.
