S T E VA L - I H M 0 2 9 V 2 Universal motor control evaluation board based on the STM8S103F2 MCU and T1235T Triac Data brief IEC 61000-4-5 pre-compliance test passed (surge up to 2 kV) RoHS compliant Description The STEVAL-IHM029V2 is a low-cost universal motor control evaluation board designed for the home appliance market, with particular focus on vacuum cleaners, food processors and power tools. This system features the 20-pin, 8-bit STM8S103F2 microcontroller running at 16 MHz (user-trimmable internal RC clock), featuring 4 KB of Flash memory, a 10-bit A/D converter, 8/16 bit timers, communication interfaces and 640 bytes of E2PROM. The power supply circuitry Features features the VIPer16L, an off-line converter with Input voltage range: 90-265 VAC, 50/60 Hz an 800 V avalanche-rugged power section, operating at 60 kHz. 12 VDC / 5 VDC auxiliary power supply based on the VIPer16L in buck converter The STEVAL-IHM029V2 especially targets topology vacuum cleaner applications with power up to Total power consumption below 300 mW in 900 W and fulfills the requirements of the standby mode 2009/125/EC EU directive, applicable starting in Maximum output power: 1500 W September 2017, thanks to the T1235T, a 12 A 20-pin, 8-bit STM8S103F2 MCU as main 800 V high performance Triac. The motor control controller is based on phase-angle. Employs zero-voltage switching (ZVS) to In order to limit in-rush current and possible synchronize MCU events with the voltage current peaks, the evaluation board features a mains soft-start routine and a smooth power change Motor driven by T1235T Triac in phase- function. The board passed the pre-compliance angle control tests for EMC directives IEC 61000-4-4 (burst up 5 power levels and standby mode selectable to 8 kV) and IEC 61000-4-5 (surge up to 2 kV). In by potentiometer standby mode, the STEVAL-IHM029V2 has an 5 LEDs to display the power level of the overall power consumption below 300 mW. board RUN LED to indicate the board is functioning Standard in-circuit programming connector IEC 61000-4-4 pre-compliance test passed (burst up to 8 kV) February 2015 DocID027368 Rev 1 1/4 www.st.com For further information contact your local STMicroelectronics sales office ++ ++ Schematic diagram STEVAL-IHM029V2 1 Schematic diagram Figure 1: STEVAL-IHM029V2 circuit schematic GSPG140 1151535SG GND 9 VDD 4 NRST NRST 8 VCAP 7 VSS LIM 3 COMP 5 2/4 DocID027368 Rev 1 VDD R26 A1 75 Gate TR1 J2 T1235 T-8T CON2 D6 A2 P6KE400CA Line 1 2 Motor VDD VDD VDD VDD VDD VDD VDD U3 STM8S103F2P6 P1 50K DL6 DL5 DL4 DL3 DL2 DL1 C23 LED LED LED LED LED LED 10n 1 BEEP /UART1 CK/PD4(HS) 2 20 UART1 TX/AIN5/PD5(HS) PD3(HS)/AIN4/TIM2 CH2/ADC ETR 3 19 UART1 RX/AIN6/PD6(HS) PD2(HS)/AIN3 SWIM R27 820 18 PD1(HS)/SWIM 5 17 OSCIN/PA1 PC7(HS)/SPI MISO R28 820 6 16 OSCOUT/PA2 PC6(HS)/SPI MOSI 15 PC5(HS)/SPI SCK ZVS 10 14 TIM2 CH 3/(HS)PA3 PC4(HS)/AIN2/TIM1 CH 4/CLK CC O R29 820 13 PC3(HS)/TIM1 CH 3 12 PB4/I2C SCL J3 R24 11 R30 820 I2C SDA/PB5 CON4 VDD 220k C22 1n 1 R31 820 SWIM 2 VDD 3 4 NRST R25 R32 820 220k Debugger Line C12 C11 C10 1u 10n 100n V-12 D5 U1 STTH1R06 VIPer16L R1 D1 D2 L 1 7 4 DR AIN1 FB 4 7 2W 1N4007 1N4007 1 m H Line 8 2 R5 90k DR AIN2 VDD C7 ++ C6 R4 100n U2 10u 33k D4 TP1 L7905 CP 25V STTH1R06 1 -12V 2 -5V 3 GND VIN VOUT J1 CON2 VSS R3 nc 1 RV1 C1 ++ C2 ++ C3 2 4u7 4u7 300V 47n LL 22 D3 C8 C9 275V~ X2 400V 400V R2 nc C5 nc 470u470u HH STTH1R06 100u 10u MAINS 25V 16V 230V~ 50Hz C4 1n VDD TP2 0V Neutral 1
