Infineon Technologies IKCM20L60HAXKMA1

Overview

IKCM20L60HAXKMA1 from Infineon is a 3-phase intelligent power module (IPM) integrating six TRENCHSTOP™ IGBTs, anti-parallel diodes, and a SOI-based gate driver in a single DIP-24 package. It delivers 600 V blocking voltage, 20 A continuous output current, and integrated overcurrent shutdown, UVLO, and cross-conduction prevention for motor control in variable-speed drives.

For engineers reviewing the IKCM20L60HAXKMA1 datasheet, IKCM20L60HAXKMA1 pinout, IKCM20L60HAXKMA1 application, or IKCM20L60HAXKMA1 equivalent, this CIPOS™ module supports fast design of compact, EMI-robust inverter stages for white goods with open-emitter current sensing, bootstrap supply, and fault reporting via VFO.

Technical Context

The module implements three half-bridge legs with isolated high-side drivers using rugged SOI technology, enabling stable operation with up to −11 V negative VS swing at VBS = 15 V. Each leg includes shoot-through prevention logic and a minimum 380 ns internal deadtime.

It integrates bootstrap circuitry for high-side supply generation, an ITRIP comparator referenced to VSS (threshold = 0.47 V), and a latched fault output (VFO) that signals under-voltage (VDD < 10.4 V) or overcurrent events with 1 µs minimum fault-clear time.

FAQ

What is the maximum allowable DC bus voltage for IKCM20L60HAXKMA1?

The absolute maximum DC link voltage between P and N is 500 V for surge conditions, but the recommended operating voltage is limited to 400 V continuous. The datasheet explicitly states that the bus voltage must not exceed 450 V under normal operation, and sustained operation above this level risks premature failure of the integrated IGBTs and internal isolation barriers.

How does the ITRIP function interface with external current sensing?

The ITRIP pin accepts a voltage signal referenced to VSS, typically derived from a shunt resistor placed between NU/NV/NW and VSS. With a fixed 0.47 V threshold and 530 ns noise filter, it detects overcurrent events without external comparators. The module shuts down all six outputs within 1000 ns after threshold crossing, and requires ≥40 µs fault-clear time before reset.

Can IKCM20L60HAXKMA1 operate without external bootstrap components?

Yes-the module integrates bootstrap functionality for all three high-side drivers. External bootstrap diodes and capacitors are still required per phase, but the internal charge-pump control and level-shifting circuitry eliminate the need for external gate driver ICs or isolated supplies. The VB/VS pins accept standard 15 V bootstrap rail voltages with UVLO thresholds at 10.4 V (falling) and 12.1 V (rising).

Is the VFO pin active-high or active-low, and what external components are needed?

VFO is an open-drain, active-low fault indicator. An external pull-up resistor (typically 4.7–10 kΩ to VDD) is mandatory to generate a valid logic-high state during normal operation. When a fault occurs-either VDD UVLO or ITRIP activation-VFO pulls low and remains latched until the fault condition clears and the internal 40 µs timer expires.
