Infineon Technologies IM12B15CC1XKMA1

Overview

IM12B15CC1 from Infineon is a fully isolated 1200 V, 15 A three-phase CIPOS™ Maxi Intelligent Power Module (IPM) integrating TRENCHSTOP™ IGBT7 S7 devices, emitter-controlled diodes, and a 6-channel SOI gate driver. It delivers motor phase outputs (U/V/W), open-emitter low-side emitters (NU/NV/NW), integrated NTC thermistor (VTH), overcurrent protection (ITRIP), and programmable fault-clear timing (RFE). Designed for low-power variable-speed drives in HVAC fans, pumps, and servo systems.

For engineers reviewing the IM12B15CC1 datasheet, IM12B15CC1 pinout, IM12B15CC1 application, or IM12B15CC1 equivalent, key selection criteria include its 1200 V blocking voltage, ±15 A continuous current rating at TC = 80°C, -40 to 125°C operating case temperature range, accessible low-side emitter pins for shunt-based phase current sensing, and integrated bootstrap functionality with -11 V allowable negative VS potential at VBS = 15 V.

Technical Context

The IM12B15CC1 implements a three-phase inverter topology with six independently controlled IGBTs driven by a rugged SOI-based gate driver featuring cross-conduction prevention, 360 ns minimum deadtime insertion, and Schmitt-trigger inputs compatible with 3.3 V logic. Its high-side floating supply architecture uses bootstrap capacitors referenced to VS(U/V/W), supporting up to -11 V transient negative VS swing relative to VSS.

Protection functions are hardware-embedded: undervoltage lockout on both VDD (11.2 V fall threshold) and VBS (10.2 V fall threshold), overcurrent shutdown triggered by ITRIP (0.5 V threshold, 500 ns noise filter), and thermal monitoring via direct-access NTC output (VTH). Fault response includes simultaneous turn-off of all six switches and programmable latch-clear timing via external RC on RFE.

FAQ

What is the maximum allowable DC-link voltage for IM12B15CC1?

The absolute maximum DC-link supply voltage (VPN) is 900 V under normal operation, with a surge rating of 1000 V for short transients. Exceeding 900 V continuously risks exceeding the 1200 V IGBT blocking rating due to voltage spikes and parasitic inductance effects, potentially triggering premature failure.

How is phase current measured using NU, NV, and NW pins?

NU, NV, and NW are dedicated low-side emitter terminals that provide isolated access to each IGBT emitter path. A precision shunt resistor placed between each pin and VSS enables direct per-phase current sensing. Layout must minimize trace inductance and keep VSS return paths short to avoid measurement error from L·di/dt voltage drops.

Can the RFE pin be used solely as a fault output without programming clear time?

Yes - RFE operates as an open-drain fault indicator by default. When a fault occurs (UVLO or ITRIP), RFE pulls low. No external RC is required for basic fault signaling. The programmable clear function activates only when an external pull-up resistor and capacitor are added; otherwise, the latch remains until VDD is cycled.

Does IM12B15CC1 require external bootstrap diodes?

No - the module integrates bootstrap diodes and supports external bootstrap capacitors only. The internal diodes charge the VB-to-VS capacitors during low-side conduction, eliminating the need for discrete high-voltage bootstrap diodes and simplifying PCB layout and reliability validation.
