STEVAL-IHM020V1 demonstration board based on the STCC08 AC switch failure mode detector
Introduction
The STEVAL-IHM020V1 demonstration board (see Figure 1) provides a means to evaluate the performance of the STCC08, which is an AC switch failure mode detector and an AC power switch driver. The device is dedicated to driving up to 10 mA IGT AC switches (ACS, ACST and TRIACs), and detecting any switch failures. This solution embeds a switch driver and an AC switch state detector. It contributes to system safety by monitoring AC switches driving sensitive loads such as drain pumps, door locks, heaters, cooling fans, and compressors. Figure 1.

Block diagram description
Figure 4 shows the block diagram of the STCC08. It includes a "gate driver" block to control the AC switch, a "power switch signal shaping" block used to read the AC switch state and a buffer able to send the AC switch state to the MCU (AVF DRIVER). This signal should be analyzed by the MCU, which can power-off the application in hazardous situations (for example, to open a relay (SW) placed in the front-end of the application - see Figure 5).

Gate driver
The STCC08 can control up to 10mA IGT TRIACs, ACST and ACS through a "GATE DRIVER" block designed:
to drive the AC switch according to the IN control input state: For IN = "1" = VCC: AC switch turn on For IN = "0" = GND: AC switch turn off
to regulate the gate current of the AC switch, thanks to the internal current controller
2.3
ACS failure detection
External resistors (R1, R2, R3 and R4) sense the voltage across the ACS. Using these resistors, the STCC08 constantly monitors the ACS state. Knowing the STCC08 IN input state, the ACS state can be deduced by analyzing the AVF signal. Figure 6 gives the ACS state according to the AVF signal state and the IN signal state.

Features
ST7LITE39F2 microcontroller
The 8-bit MCU used in this board is the ST7LITE39F2. It belongs to the ST7 family of microcontrollers, and offers a large number of features at minimum cost.
The peripheral hardware requirements are reduced to a minimum: No quartz or external resonator is used. Instead, an internal RC-oscillator in the ST7LITE3 is used to generate the clock No external RESET circuit is used Software watchdog activation RC oscillator selection PLL disabled Low voltage detection selection
In the MCU firmware, four options must be set:
Note:
The MCU firmware has been developed only to evaluate the STCC08 device and is not compliant with the class B (IEC60335-1 Ed4) requirements.
3.2
DC capacitive power supply
A DC capacitive power supply is used on the board. One peculiarity of this DC power supply is that it is "negative". The VCC terminal is connected to neutral. This means that the GND voltage is 5 V below neutral. Such a connection is mandatory to drive the ACS. Indeed, the ACS can only be triggered by a negative current (i.e. sourced from the gate). The maximum average current absorbed by the board is about 44 mA (see Table 3). In this case, a 2.2 F C16 capacitor value has been used to ensure that the board works correctly in the worst application conditions (230 V/110 VRMS line voltage 10% and VCC 10%).

Note that a 43.2 RIG resistor (R23) value is used. In this case, the minimum ambient temperature must be 0 C in order to work correctly the board. For lower ambient

Features temperatures, please refer to application note AN2716 to redefine the RIG resistor, and STCC08 consumption to redefine the C16 capacitor value. To reduce the surge current when the board is powered, a 39 R14 resistor is connected in series with the C16 capacitor. Moreover, note that for 110 VRMS AC line voltage, the VCC decreases (3.8 V), but the STCC08 demonstration board remains completely functional. The minimum power supplied to the STCC08 must be higher than 3.3 V.

Getting started
Warning: The demonstration board is not electrically isolated from the AC input. The MCU is directly linked to the mains voltage. No insulation is ensured between the accessible parts and the high voltage. The STCC08 demonstration board must be used with care and only by persons qualified to work with electricity at mains voltage levels.
Any measurement equipment must be isolated from the mains before powering the board. To use an oscilloscope with the demonstration board, it is safer to isolate it from the AC line. This prevents electric shocks which can occur as a result of touching any single point in the circuit, but does not prevent shocks when touching two or more points in the circuit. There is no insulation varnish on solder points. Care should be taken when performing measurements (for example, voltage probes must be connected only when the line and the power supply voltages are removed).

Using the demonstration board
UM0583
To operate the STCC08 board correctly and at each test, perform the following procedure first: Place the "STCC08 CNTRL" switch (SW5) to the "OFF" position Set the "N DIODE MODE (SW2)" and "P DIODE MODE (SW3)" switches to the "NO" position Put the "OPEN LOAD" (SW1) switch in the "NO" position Set the "OPEN ACS" (SW4) switch to the "NO" position Connect the AC mains wire to the AC line connector (J1). In this case, all LEDs must be off Place all mechanical switches (SW1, SW2, SW3 and SW4) in the "NO" position Put the "STCC08 CNTRL" switch (SW5) in the "ON" position The "STCC08 CNTRL" LED (D5) and the "ON" LED (D9) must be on The light bulb must be on Set the "N DIODE MODE" (SW2) or "P DIODE MODE" (SW3) switch to the "YES" position, SW1and SW4 to the "NO" position and SW5 to the "OFF" position In this case, the "DIODE" (D6) LED is on Put the "N DIODE MODE" (SW2) and "P DIODE MODE" (SW3) switches in the "YES" position, SW1and SW4 in the "NO" position and SW5 in the "OFF" position In this case, the "CC" LED (D8) is on Place the "STCC08 CNTRL" switch (SW5) in the "ON" position and all mechanical switches (SW1, SW2, SW3 and SW4) in the "NO" position Put the "OPEN ACS" (SW4) switch in the "ON" position In this case, the "OPEN" LED (D7) and "STCC08 CNTRL" LED (D9) is on Place the "OPEN LOAD" (SW1) switch in the "YES" position (this disconnects the AC load) and use the previous procedures to see the AC switch (ACS) state is detected whatever the AC load state (AC load connected or disconnected)
To turn on the AC switch:
To simulate a diode mode of the ACS:

Demonstration board immunity test
The AC line input X2 capacitor C15 (10 nF) is used to help avoid triggering the AC switch (ACS108-6S). The MCU program reads the AVF signal at each AC line peak voltage (see Figure 12). The AC switch state detection is deducted if the AVF signal remains at the same level for three consecutive AC line cycles. Figure 12. AVF signal detection

The demonstration board and mains wires are placed 10 cm above the ground reference. The mains wire is shorter than 1 m. Each operating cycle has been tested (load OFF and ON). The burst withstanding level is higher than 4 kV without spurious triggering of the ACS or ST7Lite3 MCU loss, whatever the coupling mode (to L, N, PE, etc.).

Recommendations for improving application immunity
To improve application EMC performance, the software must be EMC-oriented (for more information please refer application note AN1015):
Auto-recover y routine. At each RESET interrupt, the program must check if the data in the RAM are stored as scheduled. Indeed, a RESET can occur without the supply voltage having fallen below VRM (data retention parameter). In this case, a complete startup is not necessary, and the program can continue working with the previous RAM
16/23
UM0583
IEC 61000-4-4 Burst immunity test data. This maintains the previous switch state, for example, when a RESET occurs due to an EMI problem. If, when checked, the RAM registers are not as expected, a complete initialization procedure is launched. If the RAM area is adequate, then a "smart reset" can be performed. Only the registers which are used to store internal subroutine variables are cleared, and only the main registers keep their previous values (AC switch status, AC switch control, etc)
Use the watchdog properly. Enable the watchdog as soon as possible after reset and never refresh the watchdog in an interrupt routine Secure the unused program memory area. Fill the unused memory locations with code that forces a watchdog reset or jumps to a known program location if you do not want to generate a reset Input filtering. Its recommended to read the AVF signal during several AC line cycles.
