Infineon Technologies IRAMS06UP60A

Overview

IRAMS06UP60A from Infineon Technologies (formerly International Rectifier) is a fully isolated 3-phase inverter IPM integrating six IGBTs, gate drivers, bootstrap diodes, temperature monitoring, and overcurrent protection for appliance motor drives. It delivers 6A RMS phase current at 600V blocking voltage, supports 20 kHz PWM switching, and operates across −40°C to +150°C junction temperature with 2000 V_RMS/1 min isolation.

For engineers reviewing the IRAMS06UP60A datasheet, IRAMS06UP60A pinout, IRAMS06UP60A application, or IRAMS06UP60A equivalent, key selection factors include its integrated thermal shutdown via NTC thermistor, matched propagation delays (470 ns turn-on / 615 ns turn-off), cross-conduction prevention logic, and single-polarity 15 V supply requirement for simplified system-level motor control design.

Technical Context

The IRAMS06UP60A implements a 3-phase bridge topology with three half-bridge channels, each featuring low-V_CE(sat) non-punch-through IGBTs (1.45–1.85 V @ 3 A, 25°C) and fast recovery freewheeling diodes. Its driver IC (based on IR21365 architecture) provides Schmitt-triggered inputs, undervoltage lockout on both VCC and VBx supplies, and built-in dead-time generation (290 ns).

Thermal management is enabled by an internal 12 kΩ NTC thermistor (B = 4250 K, R₂₅ = 100 kΩ ±3%) connected to the T/ITRIP pin, with overcurrent detection triggering a 750 ns propagation delay to shut down all six switches. Isolation is achieved via reinforced creepage/clearance in the fully isolated DIP-26L package.

Manufacturer

Infineon Technologies is a global semiconductor leader specializing in power management, automotive, and industrial control solutions, with deep expertise in IGBT and IPM design since the acquisition of International Rectifier in 2015.

The IRAMS series was developed specifically for cost-sensitive, safety-critical white goods motor drives-emphasizing integration density, thermal reliability, and functional safety compliance (IEC 61800-5-1) without external protection components.

FAQ

What is the maximum recommended DC bus voltage for IRAMS06UP60A?

The absolute maximum V₊ (positive bus input) is 450 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage to IGBTs and internal drivers. For 230 V AC line applications, full-wave rectification yields ~325 V DC; derating to 450 V provides 38% margin against transients and ripple peaks.

How does the T/ITRIP pin function in overcurrent versus temperature monitoring?

T/ITRIP serves dual roles: as an analog input for the internal 12 kΩ NTC thermistor (providing die temperature feedback), and as a comparator input for external current-sense voltage. When either signal exceeds 4.3 V (typical), the driver IC triggers immediate shutdown of all six switches within 750 ns, with automatic recovery only after reset via EN pin or power cycle.

Can IRAMS06UP60A operate with a single 15 V supply, or are separate VCC and VBx supplies required?

Only one 15 V supply (VCC) is required for logic and low-side drivers; high-side drivers are self-powered via bootstrap capacitors charged through integrated diodes from VSx outputs. This eliminates need for isolated auxiliary supplies, simplifying power architecture and reducing bill-of-materials cost by ~30% compared to discrete gate driver solutions.

What is the purpose of the LE1–LE3 pins, and how should they be connected?

LE1–LE3 are low-side emitter terminals for Phases U, V, W respectively. They must be connected together externally to form the common emitter node (COM), which serves as the return path for phase currents and the reference for LINx inputs. This connection is mandatory for proper current sensing and driver biasing-floating or individually grounded emitters will cause malfunction or device failure.
