STMicroelectronics STEVAL-IPM08B

Overview

STEVAL-IPM08B from STMicroelectronics is an evaluation board designed to demonstrate and accelerate development with the STGIB8CH60TS-L SLLIMM™-2nd series intelligent power module - a fully isolated 3-phase IGBT inverter bridge (12 A, 600 V) integrating high- and low-side gate drivers, bootstrap diodes, short-circuit protection, smart shutdown logic, and dual temperature sensing (NTC + analog TSO). It supports TTL/CMOS 3.3 V/5 V inputs and targets compact, high-efficiency motor drives up to 20 kHz switching frequency.

For engineers reviewing the STEVAL-IPM08B datasheet, STEVAL-IPM08B pinout, STEVAL-IPM08B application, or STEVAL-IPM08B equivalent, this board enables rapid validation of gate drive timing, fault response (OC/UVLO), thermal monitoring integration, and PWM control interface for appliance and industrial inverter designs - with direct MCU coupling and no optocouplers required.

Technical Context

The STEVAL-IPM08B implements the STGIB8CH60TS-L IPM in SDIP2B-26L package, featuring integrated trench-gate field-stop (TFS) IGBTs rated for 600 V V_CES, 12 A continuous collector current (T_C = 25 °C), and 5 µs short-circuit withstand time at V_CE = 300 V. Its control section includes independent high-side (V_CCH) and low-side (V_CCL) supplies, hysteresis-enabled logic inputs, and a comparator-based overcurrent detection path feeding the open-drain SD/OD pin.

Thermal management is supported via two independent sensing paths: an analog voltage-output temperature sensor (TSO, 0.974–1.345 V at 25 °C) and a UL-recognized 85 kΩ NTC thermistor (T1/T2 pins). The board provides layout-optimized decoupling (C_boot, C_VCC, C_SD), RC filtering per input, and Zener clamping on V_CC/V_BOOT lines per ST's application guidelines.

FAQ

What is the primary purpose of the STEVAL-IPM08B evaluation board?

The STEVAL-IPM08B is a ready-to-use hardware platform for evaluating and prototyping with the STGIB8CH60TS-L intelligent power module. It provides pre-routed PCB traces, optimized decoupling, thermal sensing interfaces (TSO and NTC), fault signaling (SD/OD), and direct MCU-compatible logic-level inputs - enabling immediate functional validation of 3-phase inverter behavior without custom layout effort.

Does the STEVAL-IPM08B support direct connection to a 3.3 V microcontroller?

Yes - the board accepts 3.3 V or 5 V TTL/CMOS logic inputs on all HINx and LINx pins, with built-in 100 kΩ pull-down resistors and hysteresis to ensure noise immunity. No level-shifting circuitry is required, and the SD/OD pin can be pulled up directly to the MCU's 3.3 V rail using an appropriate resistor (≤1 kΩ for ≤5 mA sink current).

How does the smart shutdown function operate on this board?

The STEVAL-IPM08B demonstrates the STGIB8CH60TS-L's smart shutdown architecture: when overcurrent is detected via the CIN comparator, the internal logic immediately forces all LVGx outputs low (<24 µs delay), independent of external RC timing on the SD pin. Simultaneously, the SD/OD open-drain output activates, allowing the MCU to latch the fault condition while maintaining fast, deterministic protection response.

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

Yes - the STEVAL-IPM08B exposes both the analog TSO voltage output (pin 17) and the NTC terminals (T1/T2, pins 25/26) with dedicated decoupling options (CTSO and COT). Designers may use either or both: TSO offers fast linear voltage feedback for real-time die temperature estimation, while the NTC provides robust, standards-compliant thermal cutoff capability compliant with UL 1434 and CA 4 requirements.
