STMicroelectronics STEVAL-CTM009V1

Overview

STEVAL-CTM009V1 from STMicroelectronics is a complete 5 kW, 48 VDC three-phase inverter evaluation kit for industrial motor control, integrating power (STEVAL-CTM004V1), bulk capacitance (STEVAL-CTM005V1), gate driving (STEVAL-CTM006V1), and current sensing (STEVAL-CTM008V1) boards. It features 36× STH310N10F7/STH315N10F7 100 V, 1.9–2.1 mΩ H²PAK-6 MOSFETs, L6491 4 A gate drivers, 22× 270 μF/100 V electrolytic capacitors, and configurable HTFS 200-P-based phase/bus current sensing.

For engineers reviewing the STEVAL-CTM009V1 datasheet, STEVAL-CTM009V1 pinout, STEVAL-CTM009V1 application, or STEVAL-CTM009V1 equivalent, this kit supports rapid validation of low-voltage, high-current motor drives in forklifts, golf carts, and power tools - with modular board interconnection, ST MCU compatibility via 34-pin motor control connector, and integrated overcurrent/overtemperature/overvoltage protection.

Technical Context

The kit implements a fully assembled, stackable three-phase inverter stage: the STEVAL-CTM004V1 power board uses insulated metal substrate (IMS) construction with 6× H²PAK-6 MOSFETs per phase (total 36 devices), decoupled 2.2 Ω gate resistors, and ground-referenced shunt sensing. Thermal monitoring is provided by three NTC thermistors per phase.

STEVAL-CTM006V1 provides isolated high-current gate drive using three L6491 ICs (4 A sink/source), integrated comparator-based protections, and a standardized 34-pin ST motor control interface. Current sensing on STEVAL-CTM008V1 supports both DC bus and three-phase AC currents via unmounted ICS options and external VREF override capability.

FAQ

Is STEVAL-CTM009V1 supplied as a single assembled unit or separate boards?

STEVAL-CTM009V1 is delivered as four discrete, interconnectable PCBs: STEVAL-CTM004V1 (power stage), STEVAL-CTM005V1 (capacitor bank), STEVAL-CTM006V1 (gate driver), and STEVAL-CTM008V1 (current sensing). Mechanical mounting hardware and interboard cabling are included for system integration.

Which ST microcontrollers are compatible with the STEVAL-CTM009V1 driver board interface?

The STEVAL-CTM006V1 board features a standardized 34-pin ST motor control connector supporting STM32G4, STM32F3, and STM32F4 series MCUs with advanced timer peripherals (e.g., TIM1/TIM8 complementary outputs, dead-time insertion, and ADC trigger synchronization).

Can the current sensing board (STEVAL-CTM008V1) be used without populating the ICS components?

Yes - STEVAL-CTM008V1 supports DC current sensing in "ICS not mounted" configuration, where external current transducers (e.g., LEM HTFS 200-P) connect directly to the board's differential inputs. The internal reference can be overridden via external VREF, enabling precise gain and offset calibration.

Does the kit include thermal management hardware beyond NTCs?

No dedicated heatsinks or forced-air cooling hardware is included. The STEVAL-CTM004V1 power board uses an insulated metal substrate (IMS) for enhanced thermal conduction, and thermal protection relies solely on the three onboard NTC thermistors per phase - users must implement external heatsinking or airflow based on load duty cycle and ambient conditions.
