Board features and objectives
1.1 Objectives
The board is designed for promotion of a complete solution for home appliance applications
based on STMicroelectronics™ components. Special emphasis is placed on demonstration
of the robust full 3.3 V solution. Robustness is demonstrated on 4 kV level in class A during
IEC-61000-4-4 (burst) test.
This board also allows designers to check AC switches control feasibility with a 3.3 V supply.
Gate currents can be measured and compared to the information given in AN2986.
Promoted parts are
STM32F100C4T6B - value line 32-bit MCU
T1635H-6T - 16 A 600 V 35 mA high temperature Snubberless™ Triac in TO-220
package
ACST1635-8FP - 16 A 800 V high temperature overvoltage protected AC switch in
TO-220 FPAB package
ACS108-8SA - 0.8 A 800 V 10 mA overvoltage protected ACS device in TO-92
package
Z0109MA - 1 A standard 10 mA 4Q Triac in TO-92 package
VIPer16L - an offline converter with 800 V avalanche rugged power section operating
at 60 kHz.
The ACS108 and Z0109 are controlled in ON/OFF mode with the buttons. These devices
control small loads like valves, pumps, and door locks.
The T1635H and ACST16 are controlled in phase control mode with potentiometers. These
devices control high power loads like drum motors or heating resistors.
