Product details

Overview

IM12B20EC1 from Infineon Technologies is a fully isolated 1200 V, 20 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 control for low-power variable-speed drives with built-in overcurrent shutdown, undervoltage lockout, NTC thermistor output, and open-emitter low-side emitter pins for phase current sensing. Used in HVAC fan/pump drives and servo/GPI motor controllers.

For engineers reviewing the IM12B20EC1 datasheet, IM12B20EC1 pinout, IM12B20EC1 application, or IM12B20EC1 equivalent, key selection criteria include its 1200 V blocking voltage, ±20 A rated collector current at TC = 80°C, integrated bootstrap functionality, -11 V allowable negative VS potential, and programmable fault-clear timing via RFE pin RC network.

Technical Context

The IM12B20EC1 implements a six-switch three-phase inverter topology with high-side floating gate drivers powered by internal bootstrap circuits referenced to VS(U/V/W) pins. Its SOI-based gate driver provides inherent cross-conduction prevention and 360 ns minimum deadtime insertion between complementary HIN/LIN inputs per leg.

Control logic operates from a single 12.2–20 V VDD supply with undervoltage lockout (VDDUV+ = 12.2 V), while high-side supplies (VB–VS) tolerate up to 1200 V offset and transient -50 V negative VS potentials. Overcurrent protection triggers at 0.5 V on ITRIP with 500 ns noise filtering and latched shutdown.

Key Specifications

Parameter	Value and Actual Design Meaning
Blocking Voltage	1200 V - Enables operation with 900 V DC bus and 1000 V surge, suitable for industrial AC mains-fed inverters.
Rated Current	±20 A at TC = 80°C - Specifies continuous thermal-limited output for motor phase legs under real heatsink conditions.
Short-Circuit Withstand	5 µs at VDC ≤ 800 V - Defines safe turn-off window before IGBT thermal runaway under fault conditions.
Bootstrap Supply Range	VBS = -1 to +20 V - Supports robust high-side drive during fast transients and negative VS excursions down to -11 V.
Overcurrent Threshold	0.5 V on ITRIP pin - Sets precise current-limit trip point referenced to VSS, filtered to reject <500 ns noise pulses.
Thermal Resistance	Low RthJC due to DCB substrate - Enables higher power density and reduced heatsink requirements vs. standard DIP modules.
Isolation Voltage	2500 V RMS (1 min) - Provides reinforced insulation between power and control sections for industrial safety compliance.

Pinout & Package

Fully isolated Dual In-Line molded module (DIP 36x23D) with DCB ceramic substrate for low thermal resistance and RoHS-compliant lead-free terminals.

Pin/Terminal	Circuit Role	Design Meaning
VS(U), VS(V), VS(W)	High-side floating reference	Offset voltage references for U/V/W high-side gate drivers; withstands -50 V transients vs. VSS.
VB(U), VB(V), VB(W)	High-side floating supply	Bootstrap-supplied gate drive voltage inputs for each phase; operate up to 1200 V offset from VSS.
HIN(U/V/W)	High-side input	Positive-logic CMOS/TTL-compatible inputs with Schmitt trigger and 1 µs minimum pulse width requirement.
LIN(U/V/W)	Low-side input	Positive-logic inputs with internal 5 kΩ pull-down; enable direct MCU interface without external biasing.
VDD / VSS	Control supply rails	VDD powers logic and gate drivers (12.2–20 V); VSS is low-side ground reference for all control signals.
ITRIP	Overcurrent sense input	0.5 V threshold comparator input with 500 ns noise filter; latches shutdown on fault detection.
RFE	Fault clear / enable / fault out	Three-in-one pin: RC-programmable fault-clear time (~1 ms typical), active-low enable, open-drain fault output.
VTH	NTC thermistor output	Direct access to integrated NTC; requires external +5 V pull-up for analog temperature monitoring.
NU, NV, NW	Low-side emitter outputs	Open-emitter connections enabling shunt-based phase current measurement with minimal layout inductance.
U, V, W	Motor phase outputs	Three-phase AC motor connection points; tied to IGBT emitters and diode anodes internally.
P	Positive DC bus input	High-current input for 900 V DC link; connects to high-side IGBT collectors and freewheeling diode cathodes.

Key Features

Feature	Design Value
Integrated Bootstrap Circuitry	Eliminates external bootstrap diodes/capacitors per phase, reducing BOM count and PCB area in compact inverter designs.
Cross-Conduction Prevention	Hardware-level shoot-through avoidance ensures only one switch per leg activates even if both HIN/LIN are asserted simultaneously.
Programmable Fault-Clear Timing	RFE pin RC network (e.g., 1 MΩ + 2 nF) sets auto-restart delay after overcurrent/UV fault, enabling configurable system recovery behavior.
Open-Emitter Low-Side Outputs	NU/NV/NW pins allow precision shunt resistor placement directly at emitter nodes, minimizing parasitic inductance in current-sensing paths.
Robust High-Side Floating Operation	VS pins tolerate -50 V transients and -11 V steady-state negative potential, ensuring reliable gate drive under fast switching and load dump conditions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar three-phase inverter IPM applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
FST410A	1200 V, 25 A rating; uses older TRENCHSTOP™ 5 IGBTs; lacks programmable RFE fault-clear timing.	Higher current headroom but lower short-circuit ruggedness (3 µs vs. 5 µs); no integrated NTC thermistor output.	Select when peak current margin >25% is required and thermal monitoring is handled externally.
FSB50850	600 V, 15 A rating; smaller DIP-26 package; includes integrated current sense resistors instead of open emitters.	Not suitable for 900 V DC bus; limited to low-voltage BLDC/PMSM drives; eliminates need for external shunts but reduces measurement flexibility.	Select for cost-sensitive, space-constrained 24–48 V motor drives where integrated sensing suffices.

Compared with FST410A and FSB50850, the IM12B20EC1 uniquely combines 1200 V/20 A capability, programmable fault recovery, open-emitter current sensing, and integrated NTC-making it optimal for industrial HVAC and servo applications requiring both voltage headroom and diagnostic fidelity.

FAQ

What is the maximum allowable DC bus voltage for IM12B20EC1?

The absolute maximum DC link supply voltage (VPN) is 900 V under normal operation, with a 1000 V surge rating for transient events. Exceeding 900 V continuously risks exceeding the 1200 V IGBT blocking limit when combined with switching overshoot, so design margins must maintain peak bus voltage below this threshold.

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

NU, NV, and NW are low-side emitter terminals brought out separately to enable shunt resistor placement between each emitter and VSS. This configuration allows direct measurement of individual phase currents with minimal common-mode noise, provided PCB traces from NU/NV/NW to shunts are kept short and symmetric to avoid inductive voltage errors.

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

Yes-the RFE pin functions as an open-drain fault output by default. When not configured with an external RC network, it asserts low during undervoltage or overcurrent faults and remains latched until VDD is cycled or the microcontroller actively pulls RFE low to reset the latch, providing simple enable/disable control without timing components.

Does IM12B20EC1 require external bootstrap diodes?

No-integrated bootstrap diodes and charge paths eliminate the need for external bootstrap diodes. Each high-side driver (VB–VS) is self-powered via internal bootstrap circuitry; only external bootstrap capacitors (typically 0.1–0.22 µF X7R) per phase are required to sustain gate drive during continuous high-side conduction.
