Infineon Technologies IRAMX16UP60B-2

Overview

IRAMX16UP60B-2 from Infineon Technologies (formerly International Rectifier) is a 16A, 600V integrated power hybrid IC for 3-phase AC motor drives in air conditioning compressors and light industrial systems. It integrates six IGBTs with low V_CE(on) punch-through technology, three high-voltage gate drivers with bootstrap diodes, internal shunt resistor (18.1 mΩ), NTC thermistor, and protection logic including over-current trip (21–28 A), under-voltage lockout (10.6–11.6 V), and cross-conduction prevention.

For engineers reviewing the IRAMX16UP60B-2 datasheet, IRAMX16UP60B-2 pinout, IRAMX16UP60B-2 application in HVAC compressor inverters, or IRAMX16UP60B-2 equivalent for appliance motor drive modules, this page delivers verified electrical specs, thermal performance data, isolation rating (2000 V_RMS), and real-world design constraints including matched propagation delay (≤75 ns), dead time (220–360 ns), and motor power range (0.75–2.2 kW at 85–253 V_AC).

Technical Context

This HIC implements a fully isolated 3-phase inverter stage with integrated driver IC and power switches in a single SiP2 package. Its architecture combines IR's low-loss IGBTs (V_CE(on) = 1.55–2.10 V @ 8 A, 25–150°C) with an industry-standard high-speed gate driver core featuring Schmitt-triggered inputs, blanking-timed current fault detection (ITRIP), and auto-reset recovery after over-current events.

The device uses a transfer-molded structure with full creepage (3.2 mm) and thermal resistance of 3.5–4.0 °C/W (junction-to-case per IGBT). Protection functions include temperature monitoring via internal NTC (R₂₅ = 100 kΩ), short-circuit safe operating area (10 µs), and RBSOA compliance - all coordinated through shared logic referenced to COM/ITRIP.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable DC bus voltage for IRAMX16UP60B-2?

The absolute maximum V₊ rating is 450 V, and the IGBT blocking voltage is rated at 600 V. Operation above 450 V risks exceeding the recommended operating condition for the high-side floating supplies (VB1–VB3), which are limited to VS+20 V. Sustained use beyond 450 V may cause premature failure due to overstress on internal bootstrap networks and gate oxide reliability.

How does the internal ITRIP function interact with external current sensing?

The ITRIP pin accepts the differential voltage across the internal 18.1 mΩ shunt resistor. No external sensing is needed - the device compares this voltage directly to its internal 490 mV threshold. External current sensing would require removing the internal shunt path (not possible) or adding parallel resistors, which invalidates the calibrated trip point and voids protection integrity.

Can IRAMX16UP60B-2 be used with 24 V logic supply instead of 15 V?

No. The VCC absolute maximum rating is 20 V, but the undervoltage lockout (UVLO) thresholds are fixed at 10.6–11.6 V. Operating at 24 V exceeds the 20 V limit and risks permanent damage to the driver IC's internal regulators and level shifters. The recommended VCC range is strictly 12–20 V, with 15 V being the nominal and validated operating point.

What thermal interface material is recommended for mounting IRAMX16UP60B-2?

A greased flat surface with thermal compound having conductivity ≥1 W/m·K is specified in the datasheet. Standard silicone-based thermal pastes (e.g., Dow Corning TC-5122, Parker Chomerics T-grease 3600) meet this requirement. Mounting torque must be controlled to 0.5–1.0 Nm (M3 screw) to avoid package cracking or delamination while ensuring optimal thermal contact.
