This evaluation board implements an 8-line protected digital input termination with serialized state transfer for Programmable Logic Controllers. It is based on the CLT01-38SQ7 device, which enhances I/O module density by reducing dissipation (78 mW per input) and the number of opto-transistors. A LED driver is embedded in each input section. Its 6.25 MHz SPI peripheral output serializes the input state transfer to the I/O module controller. The STEVAL-IFP031V1 evaluation board can be connected in daisy chain with other STEVAL-IFP031V1 evaluation boards. The adapter board can be placed between the first STEVAL-IFP031V1 evaluation board in the chain and the STEVAL-PCC009V2 STM32x microcontroller evaluation board. This adapter offers two buses: isolated and non-isolated.

The STEVAL-IFP033V1 functions with the STEVAL-PCC009V2 or STEVAL-PCC009V1 interface board to allow evaluation of the ISO8200BQ device. A large GND area on the printed circuit board is included to minimize noise effects and ensure good thermal performance. The ISO8200BQ is a galvanic isolated 8 channel driver featuring a very low supply current. It contains two independent galvanic isolated voltage domains (VCCfor the power stage and VDDfor the digital stage). The IC is intended to drive any type of load with one side connected to ground. Independent active channel current limitation combined with thermal shutdown for each channel and automatic restart protect the device against overload. Other embedded functions include loss of GND protection which automatically turns off the outputs in case of analog ground, undervoltage shutdown with hysteresis and a reset function for immediate power output shutdown. Built-in thermal shutdown protects the chip against overtemperature and short-circuit. The channel is turned off in the overload condition and switched back on automatically once the IC temperature decreases below the reset threshold. If this condition causes the case temperature to reach the TCR limit, the overloaded channel is turned off and will only restart when case and junction temperature decreased down to the reset threshold. Non overloaded channels continue to operate normally. An internal circuit provides an OR-wired non latched common FAULT indicator signaling channel OVT. The FAULT pin is an open-drain active-low fault indication pin.

The STEVAL-IFP035V1 evaluation board is designed to help you evaluate circuit protection strategies for factory automation using digital-input current limiters between industrial sensor devices and processing units such as programmable logic controllers (PLC). The board embeds two independent CLT03-2Q3 self-powered digital input current limiters, each with two isolated channels able to drive isolated opto-coupler or non-isolated LVTTL digital input terminations. These devices also feature reduced power dissipation and improved EMI robustness for safer and more reliable operation, and to allow designers to build solutions with greater I/O module density. The board also observes other standard industry requirements such as reverse polarity operation and one-minute overvoltage tolerance, and jumpers are included to generate test pulses along any of the lines to verify normal operation.

The STEVAL-IHM021V2 demonstration board implements a 100 W, 3-phase inverter for field-oriented control (FOC) of permanent magnet synchronous motors (PMSM). The 3-phase inverter bridge is based on the STD5N52U power MOSFET with enhanced fast body-drain recovery diode in a DPAK package, and the L6390. The L6390 represents the latest in high-voltage half-bridge gate drivers featuring an integrated comparator for hardware protection against overcurrent, overtemperature, etc. The device also features an embedded operational amplifier suitable for advanced current sensing. The STEVAL-IHM021V2 has been specifically designed to achieve fast and accurate conditioning of the three shunt resistor-based motor current feedback network, matching the requirements typical for high-end applications such as field-oriented motor control. As an alternative to the STD5N52U, the STGD6NC60HD or STGDL6NC60DI IGBT devices may also be used on the board for frequencies lower and higher than 10 kHz, respectively. In either case, no replacement of the switches driving the network is required. The board is compatible with 110 and 230 Vac mains, and includes a power supply stage using the VIPer12A-E (in buck configuration) to generate the +15 V and +3.3 V supply voltage required by the application. The board can be interfaced with the STM3210B-EVAL (STM32 microcontroller demonstration board) through the dedicated motor control connector.

The STEVAL-IHM023V3 evaluation board implements a 1 kW three-phase motor control application featuring L6390 high and low-side driver and the STGP10H60DF IGBT. The evaluation board is an AC-DC inverter that generates a three-phase waveform for driving two- or three-phase motors such as induction motors or PMSM motors up to 1000 W, with or without sensors. The STEVAL-IHM023V3 is a universal, fully evaluated and populated design consisting of a three-phase inverter bridge based on STMicroelectronics’ 600 V IGBT STGP10H60DF in a TO-220 package mounted on a heatsink, and the L6390 high-voltage high-side and low-side driver featuring an integrated comparator for hardware protection features such as overcurrent and overtemperature. The driver also integrates an operational amplifier suitable for advanced current sensing. Thanks to this advanced characteristic, the system achieves accurate and fast conditioning of the current feedback, addressing the typical requirements of field-oriented control (FOC). The board has been designed to be compatible with a single-phase mains, supplying from 90 VAC to 285 VAC or from 125 VDC to 400 VDC for DC voltage. With reconfiguration of the input sourcing, the board is suitable also for low-voltage DC applications up to 35 VDC.

The goal of the STEVAL-IHM028V2 product evaluation board is to present a universal, fully tested and populated design consisting of a 3- phase inverter bridge based on the 600 V, 17 A intelligent power module STGIPS20C60. The IPM itself consists of short-circuit rugged IGBTs with negative temperature co-efficiency. It also contains a wide range of auxiliary functions like undervoltage lockout and smart shutdown. Thanks to these advanced characteristics, the system has been specifically designed to achieve accurate and fast conditioning of the current feedback, matching the typical requirements for field oriented control (FOC). This board can be used to evaluate a wide range of applications such as HVAC (air conditioners), power white goods and high-end single-phase power tools.

The STEVAL-IHM032V1 demonstration board is a 3-phase inverter designed to perform both the field-oriented control (FOC) of sinusoidal-shaped back-EMF permanent magnet synchronous motors (PMSMs) and trapezoidal control of brushless DC (BLDC) motors with or without sensors, with nominal power up to 150 W. This flexible, open, high-performance system based on the L639x and STGD3HF60HD is specifically designed to achieve fast and accurate conditioning of the current feedback, thereby matching the requirements typical of high-end applications such as field-oriented motor control. The board is compatible with 110 and 230 Vac mains, and includes a power supply stage with the VIPer12A-E (in flyback configuration) to generate the +15 V and +3.3 V supply voltage required by the application. Finally, the board can be interfaced through a dedicated connector with the STM3210xx-EVAL (STM32 microcontroller demonstration board), STEVAL-IHM022V1 (high-density, dual motor control demonstration board based on the STM32F103ZE microcontroller), and with the STEVAL-IHM033V1 (control stage based on the STM32F100 microcontroller suitable for motor control).
