The EVAL6470H-DISC is a high performance evaluation and demonstration board featuring the STMicroelectronics ST6470H TRIAC driver IC with on board optically isolated signals suitable for controlling AC voltage. The board is designed to demonstrate the key features of the ST6470H as well as providing a framework for developing a wide variety of TRIAC control applications. The board uses an on-board DC power supply, motor control IC, and driver circuit for driving the TRIAC and for providing integrated single-chip AC control.

The EVAL6470H-DISC is designed for two primary application fields. The first involves controlling an external motor by driving the TRIAC which actuates the motor through an on-board potentiometer. This is typically used for applications such as industrial control, appliances, motorized gate control, and home automation. The second application field involves controlling an external AC voltage, such as a lights, air conditioning, and various other devices. It can also be used as a standalone board for controlling AC power for a variety of prototype development applications.

The EVAL6470H-DISC works by connecting a DC power supply to the board and then providing signals to the TRIAC control inputs. The board can be configured to allow for both manual control and automated control. In manual control, the user provides commands to the externally connected TRIAC driver which then passes the signals to the TRIAC. The driver IC then converts the signals into a voltage that is suitable for controlling the TRIAC. In automated control, the user can use either a PLC controller or an embedded microprocessor to provide the signals to the driver IC.

The board also incorporates an on-board switching power supply and a digital controller which can be configured to provide full-wave, half-wave, and various other types of control signals for controlling an AC load. The EVAL6470H-DISC is capable of providing up to 3A of output current, which is sufficient for controlling a wide range of applications. Additionally, the board features a differential input to the TRIAC driver, which provides noise immunity and allows for greater control accuracy.

The EVAL6470H-DISC is a versatile tool for evaluation and demonstration of ST6470H TRIAC control applications. It provides an integrated package for controlling both an external motor or an external AC voltage, and features a comprehensive on-board power supply and digital control circuitry to ensure that the board can be configured for a wide variety of applications. The board is ideal for development of prototype projects and can also be used as a standalone board for demonstration of AC control applications.
