Infineon Technologies IRAM136-1060B

Overview

IRAM136-1060B from Infineon Technologies (formerly International Rectifier) is a 10A, 600V integrated 3-phase inverter hybrid IC for appliance motor drives, combining six Trench IGBTs, three high-voltage gate drivers, internal shunt resistor (33.3 mΩ), NTC thermistor, and bootstrap diodes in a single isolated SIP-5 package. It delivers programmable overcurrent protection, matched propagation delay (<75 ns), and 2000 V_RMS isolation for washing machine, refrigerator compressor, fan, and air conditioner drives.

For engineers reviewing the IRAM136-1060B datasheet, IRAM136-1060B pinout, IRAM136-1060B application, or IRAM136-1060B equivalent, key selection criteria include its integrated current sensing (±5% shunt tolerance), 3.3V/5V Schmitt-trigger logic compatibility, thermal feedback via VTH pin, and cross-conduction prevention logic - all validated for 0.25–0.75 kW AC motor control at 85–253 V_AC.

Technical Context

This hybrid IC integrates a full 3-phase inverter bridge with embedded HVIC gate drivers, eliminating external bootstrap networks and discrete current-sense amplifiers. Its architecture uses matched propagation delays across all six channels and dedicated ITRIP input with 150 ns blanking time to enable precise cycle-by-cycle overcurrent shutdown.

The module employs Trench IGBTs with 1.7 V typical V_CE(sat) @ 5 A / 150°C and fast-recovery diodes (t_RR = 150 ns), paired with an internal 33.3 mΩ shunt resistor and NTC thermistor (R₂₅ = 100 kΩ, B = 4250 K) for real-time current and temperature monitoring - all referenced to COM and isolated from the power stage.

FAQ

What is the maximum continuous RMS current rating for IRAM136-1060B at 100°C case temperature?

The device supports 5 A RMS continuous phase current at T_C = 100°C, as specified in Absolute Maximum Ratings. This derating reflects thermal limits of the internal IGBTs and ensures reliable operation within the 150°C maximum junction temperature, assuming proper heatsinking and airflow per the R_th(J-C) = 4.6 °C/W specification.

How does the internal shunt resistor enable current sensing without external amplification?

The 33.3 mΩ shunt produces a differential voltage (e.g., 333 mV at 10 A) directly fed to the IFB pin, which is internally referenced to VSS. The driver IC's analog front-end provides buffered, noise-filtered output - eliminating need for external op-amps, gain resistors, or level-shifting circuits typically required with discrete shunts.

Can IRAM136-1060B operate with 3.3 V logic inputs while maintaining full timing performance?

Yes - the HIN/LIN inputs feature Schmitt-trigger thresholds (2.5 V typ. high, 0.8 V typ. low) and maintain full timing specs (≤1.15 μs propagation delay, ≤75 ns channel matching) at 3.3 V supply, verified per the Static and Dynamic Electrical Characteristics tables in the official datasheet.

What is the function of the RCIN pin, and how is it used in system design?

RCIN sets the blanking time for the ITRIP overcurrent protection circuit. A 100 kΩ resistor to VSS configures 150 ns blanking (per datasheet Figure 2), rejecting false triggers from switching transients. This eliminates need for external digital filtering or microcontroller-based debounce, simplifying fault response timing.
