Infineon Technologies IRAMS10UP60B-W

Overview

IRAMS10UP60B-W from Infineon Technologies is a 600V, 10A intelligent power module (IPM) integrating three half-bridge IGBTs, bootstrap diodes, gate drivers, and protection circuitry in a single DIP-26L package. It delivers integrated motor control for brushless DC and permanent magnet synchronous motors with built-in overcurrent, overtemperature, and undervoltage lockout functions. Used in HVAC blower drives and small industrial pumps.

For engineers reviewing the IRAMS10UP60B-W datasheet, IRAMS10UP60B-W pinout, IRAMS10UP60B-W application, or IRAMS10UP60B-W equivalent, key selection criteria include rated blocking voltage, continuous current capability, integrated protection thresholds, thermal resistance, and gate drive compatibility with standard 3.3V/5V logic controllers.

Technical Context

This IPM implements six independent gate drivers with matched propagation delays (<150 ns) and active Miller clamp functionality to prevent false turn-on. Each half-bridge includes dedicated fault reporting via a single open-collector FAULT pin, with internal comparators monitoring VCE for overcurrent and NTC thermistor voltage for temperature.

The module uses low-loss TRENCHSTOP™ IGBTs and soft-recovery anti-parallel diodes optimized for 15–20 kHz PWM operation. Its isolated substrate enables direct heatsink mounting without additional insulation, and the integrated bootstrap diodes eliminate external high-voltage bootstrap components.

FAQ

What is the maximum recommended PWM switching frequency for IRAMS10UP60B-W?

The module is characterized for reliable operation up to 20 kHz with standard gate resistors (10 Ω turn-on, 22 Ω turn-off). At 20 kHz, total switching losses remain within thermal limits at 10 A continuous load with 100°C case temperature. Operation above 20 kHz increases conduction loss dominance and requires derating to 7.5 A to maintain safe junction temperature.

Does IRAMS10UP60B-W require external bootstrap capacitors?

Yes - external 0.22 µF ceramic bootstrap capacitors (X7R, 50 V rating) are required per phase between VBx and VSx pins. The integrated bootstrap diodes eliminate external diodes, but capacitors must be placed within 5 mm of the module pins to minimize loop inductance and prevent gate drive instability during high dI/dt transitions.

How is overtemperature protection implemented?

Overtemperature protection uses an internal NTC thermistor embedded near the IGBT die. The module provides a dedicated TH pin that outputs a voltage proportional to temperature (10 kΩ at 25°C, β = 3435 K). Protection triggers at 150°C junction temperature, pulling the FAULT pin low and disabling all gate outputs until reset via VDD cycling or logic input reinitialization.

Can IRAMS10UP60B-W drive a PMSM using field-oriented control (FOC)?

Yes - the module supports FOC when paired with a controller capable of generating three independent PWM pairs with dead-time insertion and current-sense synchronization. Its matched propagation delays (<150 ns) and fast fault response (<2.5 µs) enable precise current vector control at 10–15 kHz carrier frequencies, meeting timing requirements for torque ripple <5% in 0.5–1.5 kW PMSM applications.
