1 / 4 page Data brief For further information contact your local STMicroelectronics sales office. December 2010 Doc ID 18344 Rev 1 1/4 4 STEVAL-IHT005V1 3.3 V control of ACS/Triac with STM32 Features ■ Complete solution for -3.3 V control ■ Input voltage range: 90-265 VAC, 50/60 Hz ■ Negative 6 V/3.3 V VDC auxiliary power supply based on the Viper16L in buck-boost topology ■ Total power consumption in standby mode is lower than 0.3 W for 264 V / 50 Hz ■ 48-pin, 32-bit value line family STM32F100C4T6B MCU as main controller ■ Zero voltage switching (ZVS) interrupt to synchronize MCU events with voltage mains ■ 1x T1235H-6T and ACST12-7C for phase control of high power loads ■ 5 discrete power level states with soft change for phase angle controlled devices ■ 1x Z0109 and 3x ACS108 for full wave control of low power loads ■ 1x relay for demonstration of the board noise robustness ■ “Red” LED to show the board is supplied from mains ■ “Green” LED for each ACS/ACST/Triac to show the device is turned on ■ IEC 61000-4-4 pre-compliance test passed (burst up to 8 kV) ■ IEC 61000-4-5 pre-compliance test passed (surge up to 2 kV) ■ RoHS compliant Description The STEVAL-IHT005V1 demonstration board is designed for the home appliance market, with a focus on the demonstration of a robust solution with a 3.3 V supplied 32–bit MCU. Target applications are mid-end and high-end washing machines, dishwashers, and dryers, with different kinds of ACS/Triacs. The demonstration board is based on the 48-pin 32-bit STM32F100C4T6BMCU, running at 24 MHz (RC user-trimmable internal RC clock), featuring 16 kBytes of Flash memory, 12-bit A/D converter, 5 timers, communication interfaces, and 4 kBytes of SRAM. The power supply circuitry is based on VIPer16L, an offline converter with an 800 V avalanche rugged power section, operating at 60 kHz. The power supply provides negative 6 V in buck-boost topology. The STEVAL-IHT005V1 can control two high power loads up to 2640 W, thanks to the T1235H, a 12 A 600 V high temperature Triac, and up to 1840 W ACST12-7C, 12 A 700 V overvoltage protected ACSTTM device. The high power load control is based on phase angle control. To limit the in-rush current and possible current peaks, the demonstration board features a soft-start routine and a smooth power change function for the high power loads. The STEVAL- IHT005V1 can also control 4 low power loads up to 100 W, thanks to 3 ACS108-6S, 0.8 A 600 V overvoltage protected ACSTM devices and a Z0109, 1 A standard 4 quadrant 600 V Triac. The demonstration board passed the pre-compliance tests for EMC directives IEC 61000-4-4 (burst up to 8 kV) and IEC 61000-4-5 (surge up to 2 kV). When put in standby mode, the STEVAL- IHT005V1 has an overall standby power consumption below 300 mW at 264 V / 50 Hz. STEVAL-IHT005V1 www.st.com |
