Infineon Technologies IKCM15H60HAXKMA1

Overview

IKCM15H60HAXKMA1 from Infineon Technologies is a 3-phase intelligent power module (IPM) integrating six TRENCHSTOP™ IGBTs, anti-parallel diodes, and a monolithic SOI gate driver in a fully isolated DIP-24 package. It delivers 600 V blocking voltage, 15 A continuous output current, and supports PWM switching up to 20 kHz for variable-speed motor control. Used in washing machine inverter drives, it provides open-emitter low-side emitter pins (NU/NV/NW) for phase current sensing and integrated overcurrent shutdown via ITRIP pin.

For engineers reviewing the IKCM15H60HAXKMA1 datasheet, IKCM15H60HAXKMA1 pinout, IKCM15H60HAXKMA1 application, or IKCM15H60HAXKMA1 equivalent, key selection criteria include bootstrap-enabled high-side drive (VB/VS), 0.5 µs minimum pulse width support, matched propagation delays across all six channels, -11 V allowable VS transient tolerance, and integrated cross-conduction prevention logic.

Technical Context

The module implements three half-bridge legs with independent high-side (HINx) and low-side (LINx) TTL/CMOS-compatible inputs, each driving an IGBT with integrated SOI gate driver. All six outputs feature matched on/off delay times and built-in shoot-through prevention that prioritizes the first-activated input per leg.

Protection architecture includes under-voltage lockout on both VDD (12.1 V turn-on, 10.4 V turn-off) and high-side floating supply VBS, plus overcurrent detection referenced to VSS with 0.47 V threshold and 530 ns noise filter. Fault status is reported via open-drain VFO pin requiring external pull-up.

FAQ

What is the purpose of the VS pins (1, 3, 5) and how do they differ from VB pins?

VS(U), VS(V), and VS(W) serve as floating reference potentials for their respective high-side gate drivers, enabling level-shifting relative to the motor phase voltages. Unlike VB pins-which supply positive voltage to the high-side driver-the VS pins define the local ground for each high-side channel and tolerate up to -11 V transient negative voltage versus VSS, ensuring robust operation during fast switching transitions.

Can IKCM15H60HAXKMA1 be used without external bootstrap components?

Yes. The module integrates bootstrap circuitry for high-side gate drive, eliminating the need for external bootstrap diodes and capacitors. Each VB/VS pair operates autonomously, drawing charge from the low-side switching node during conduction to maintain high-side supply voltage-reducing design complexity and improving reliability in compact inverter layouts.

How does the ITRIP protection function interact with the VFO pin?

When the ITRIP comparator detects a voltage ≥0.47 V (indicating overcurrent), it triggers a latch that disables all six gate drivers within 1000 ns and pulls the VFO pin low. VFO remains low until the fault condition clears and a minimum 40 µs reset time elapses. An external pull-up resistor is mandatory to establish valid logic-high state during normal operation.

What thermal derating applies above 80°C case temperature?

At TC = 80°C, the continuous output current rating drops from 15 A to 10 A to maintain TJ ≤ 150°C. This linear derating reflects the module's 4.96 K/W junction-to-case thermal resistance per IGBT. Heatsink design must ensure TC stays ≤80°C under full load to sustain rated current; forced air or larger copper area is recommended for sustained 15 A operation.
