STMicroelectronics STEVAL-IPM07F

Overview

STEVAL-IPM07F from STMicroelectronics is an evaluation board designed to demonstrate and validate the STGIF7CH60TS-L SLLIMM-2nd series intelligent power module - a fully isolated 3-phase IGBT inverter bridge rated at 10 A / 600 V, featuring integrated high- and low-side gate drivers, bootstrap diodes, short-circuit protection, smart shutdown, and dual temperature sensing (NTC + analog TSO). It targets motor drive applications up to 20 kHz switching frequency in washing machines, dryers, industrial fans, and pumps.

For engineers reviewing the STEVAL-IPM07F datasheet, STEVAL-IPM07F pinout, STEVAL-IPM07F application, or STEVAL-IPM07F equivalent, this board enables rapid validation of gate drive timing, fault response latency, thermal monitoring accuracy, and PWM dead-time implementation using the STGIF7CH60TS-L IPM under real-world load conditions with 3.3 V/5 V TTL/CMOS logic interfacing.

Technical Context

The STEVAL-IPM07F implements a complete 3-phase inverter reference design around the STGIF7CH60TS-L SDIP2F-26L module, supporting direct MCU connection without optocouplers via integrated HVICs. It includes dedicated RC filtering on all six logic inputs (HIN/LIN x3), configurable SD pin restart timing, and dual-path thermal feedback (analog TSO voltage output and UL-recognized 85 kΩ NTC).

Board-level features include bootstrap capacitor decoupling (Cboot + C3 per phase), VCC transient suppression (Dz1 Zener), VBOOT overvoltage clamping (Dz2), shunt-based overcurrent sensing with CIN comparator interface, and layout-optimized low-inductance power paths for P/NW/NV/NU/U/V/W terminals - all aligned with ST's DS10416 layout guidelines for EMI control and fault immunity.

FAQ

What microcontroller interfaces are supported by the STEVAL-IPM07F?

The board accepts standard 3.3 V or 5 V TTL/CMOS logic signals directly on all six gate input pins (HINU/HINV/HINW/LINU/LINV/LINW), with built-in 100 kΩ pull-down resistors eliminating external biasing. No level-shifting or isolation components are required for compatibility with STM32, PIC, or ARM Cortex-M MCUs.

How does the smart shutdown function operate on this evaluation board?

When overcurrent is detected via the external shunt resistor and CIN comparator input, the STGIF7CH60TS-L forces all LVGx outputs low within ≤24 µs - independent of external RC timing on the SD pin. The SD open-drain output then asserts low, and restart occurs only after SD voltage exceeds 0.75 V and internal timing elapses, enabling precise fault recovery control.

Can both temperature sensing methods (TSO and NTC) be used simultaneously?

Yes - the board provides parallel access to both the analog TSO voltage output (pin 17) and the dual-terminal NTC (pins 25/T2 and 26/T1). TSO delivers linear voltage vs. junction temperature (0.974–1.345 V from 25 °C), while the NTC offers UL 1434-certified resistance-based monitoring (85 kΩ @ 25 °C, 2.6 kΩ @ 125 °C), allowing redundant or application-specific thermal management.

What layout practices does the STEVAL-IPM07F implement to ensure reliable high-frequency operation?

The board follows ST's DS10416 layout rules: low-inductance power routing for P/NW/NV/NU/U/V/W, localized 100–220 nF ceramic decoupling on each VCC and VBOOT node, 1 µs RC filter on CIN, 100 ns RC filters on all six logic inputs, and single-point grounding of SGN_GND to PWR_GND near the shunt resistor - minimizing noise coupling and false fault triggering.
