产品概述
描述
The STEVAL-IHT006V1 is a low-cost demonstration board for the home appliance market. It is suitable to replace the mechanical thermostat and the incandescent light bulb in domestic refrigerators.
The system employs the 8-bit STM8S103F2 microcontroller running at 16 MHz and featuring 4 kB of Flash memory, a 10-bit A/D converter,
8/16-bit timers, communication interfaces and 640 bytes EEPROM.
The power supply circuitry is based on the VIPer16LN, an offline converter with an 800 V avalanche-rugged power section, operating at 60 kHz.
The STEVAL-IHT006V1 is designed to drive small-size or mid-size compressors up to 200 W using the ACST8, an 8 A 800 V overvoltage-protected AC switch.
Three 100 mA LEDs efficiently replace a 15 W incandescent light bulb.
The demonstration board has passed the internal tests for EMC directives: IEC 61000-4-4 (burst up to 8 kV) and IEC 61000-4-4 (surge up to 2 kV).
In standby mode, the STEVAL-IHT006V1 has a standby power consumption below 170 mW at 220 VAC 50 Hz.
