Infineon Technologies IRAM136-1561A

Overview

IRAM136-1561A from Infineon Technologies is a 600V, 15A intelligent power module (IPM) integrating six IGBTs, bootstrap diodes, gate drivers, and protection circuitry in a single DIP-26L package. It implements a 3-phase inverter stage for brushless DC and AC induction motor control, with built-in overcurrent, overtemperature, and undervoltage lockout. Used in HVAC compressors, industrial pumps, and appliance motor drives.

For engineers reviewing the IRAM136-1561A datasheet, IRAM136-1561A pinout, IRAM136-1561A application, or IRAM136-1561A equivalent, key selection criteria include integrated short-circuit protection response time, thermal resistance (R_th(j-c) = 0.45°C/W), maximum blocking voltage rating, and gate drive supply compatibility (15 V ±10%).

Technical Context

This IPM integrates three half-bridge IGBT pairs with matched gate drivers, enabling full 3-phase inverter operation without external level-shifting circuitry. Each high-side driver uses internal bootstrap diodes and supports 15 V gate drive with dedicated UVLO thresholds per channel.

Protection functions are hardware-based: desaturation detection triggers shutdown within 2.5 µs, NTC thermistor output enables system-level thermal monitoring, and fault signals are latched via open-collector FAULT pin. The module operates with logic-level PWM inputs (3.3 V/5 V compatible) and requires no external current-sense shunts.

FAQ

What is the recommended gate resistor value for IRAM136-1561A?

A 10 Ω non-inductive resistor is specified in the datasheet for optimal switching loss vs. EMI trade-off at 15 kHz PWM. Values below 5 Ω increase dV/dt stress on IGBTs; above 22 Ω extend turn-off time beyond 350 ns, risking cross-conduction in high-frequency FOC.

Does IRAM136-1561A require external current sensing?

No. The module does not integrate current sensing; motor phase current must be measured externally using shunt resistors or Hall-effect sensors. Its FAULT pin responds only to desaturation and thermal faults-not overcurrent-so closed-loop current control remains fully external.

Can IRAM136-1561A operate with 3.3 V microcontroller PWM outputs?

Yes. Input threshold voltages are VIH = 2.0 V min and VIL = 0.8 V max, making it compatible with 3.3 V CMOS logic without level shifters. The internal Schmitt-trigger inputs provide noise immunity up to 400 mV hysteresis.

What is the maximum allowable case temperature during continuous operation?

The absolute maximum case temperature is 100°C per datasheet Section 6.2. Derating begins at 85°C case temperature; at 100°C, continuous current must be reduced to 10.5 A to maintain junction temperature ≤150°C with R_th(j-c) = 0.45°C/W.
