Infineon Technologies IRAMS10UP60A

Overview

IRAMS10UP60A from Infineon Technologies (formerly International Rectifier) is a 3-phase, 10A/600V integrated power module with built-in gate drivers, bootstrap diodes, temperature monitor, and overcurrent/overtemperature shutdown. It implements non-punch-through IGBTs with 4.2°C/W junction-to-case thermal resistance per IGBT and operates from -40°C to +150°C junction temperature. Used in washing machine and refrigerator motor inverters.

For engineers reviewing the IRAMS10UP60A datasheet, IRAMS10UP60A pinout, IRAMS10UP60A application, or IRAMS10UP60A equivalent, key selection criteria include its 600V blocking voltage, 10A RMS phase current rating at 25°C, matched propagation delays (470ns turn-on / 615ns turn-off), integrated thermistor (100kΩ @ 25°C), and UL-recognized fully isolated package (2000VRMS).

Technical Context

The IRAMS10UP60A integrates six IGBTs (three high-side, three low-side) and six gate drivers into a single fully isolated module, using Plug N Drive™ architecture to eliminate external bootstrap components and simplify 3-phase inverter design. Its driver IC (based on IR21365) provides Schmitt-triggered inputs, cross-conduction prevention logic, and under-voltage lockout for both VCC and VB supplies.

Thermal protection is implemented via an internal NTC thermistor (R25 = 100kΩ ±5%, B = 4250K) connected to the T/ITRIP pin, which triggers shutdown when temperature exceeds threshold or when current exceeds 15A peak (tp < 100ms). The module supports PWM carrier frequencies up to 20kHz and delivers short-circuit safe operation for 10µs at 150°C.

Key Specifications

Pinout & Package

IRAMS10UP60A uses a fully isolated PD-94640 surface-mount package with integrated heatsink pad and M3 mounting screw holes. Thermal resistance from junction to case is specified separately for IGBTs (4.2–4.7°C/W) and diodes (5.5–6.5°C/W).

FAQ

What is the maximum recommended voltage on the T/ITRIP pin during normal operation?

The maximum recommended sense voltage at the T/ITRIP terminal under normal operating conditions is 3.3V, as specified in the datasheet Note 3. Exceeding this level risks false triggering of thermal or overcurrent shutdown. The pin has a 4.3V threshold for fault latching, but sustained operation above 3.3V may degrade long-term reliability of the internal comparator circuit.

Can IRAMS10UP60A operate with a single 15V supply for both VCC and VB rails?

No. VCC (pin 22) supplies the logic and low-side drivers with 12–20V, while VB1–VB3 (pins 1,4,7) require independent floating 15V supplies referenced to their respective VS nodes (pins 2,5,8). Using a single fixed 15V rail for VB would violate the VS offset specification and cause high-side driver failure.

How is dead time enforced between high-side and low-side switches?

Dead time is enforced by internal hardware logic within the driver IC (IR21365 derivative), with a fixed minimum value of 300ns. This is independent of external timing control and ensures that both switches in any half-bridge are never simultaneously active-even if HIN and LIN signals overlap-preventing shoot-through and device destruction.

What is the purpose of the LE1–LE3 pins, and how do they differ from COM?

LE1–LE3 provide isolated low-side emitter connections for each phase, enabling precise shunt-based current sensing without disrupting the main power path. COM (pin 12) is a common low-side return for driver logic and is not rated for high-current sensing; using it for current measurement introduces noise and measurement error due to shared return impedance.
