UM0583 Demonstration board introduction

5/23

Components on the demonstration board include:

● the STCC08 device (U1)

● the STLITE39F2 MCU (U2). The 8-bit MCU drives the AC switch through the STCC08,

analyzes the STCC08 AVF signals and powers LEDs to indicate AC switch failures

● the ACS108-6S (U3), transient voltage protected AC switch

● A capacitive DC power supply

● An ICC (in-circuit connector) (J3) to load the firmware in the MCU.

Warning: Before the board is connected to a co mputer thr ough the ICC

connector, ensure that the AC line is connected to the board through an insulated plug. Thi s is essential to a void el ectrical shock.

● A switch to simulate an AC load failure in open circuit (SW1)

● 2 switches (SW2, SW3) to simulate a diode mode f ailure in bo th polarities of the A C line

and a short-circuit of the AC switch (when SW2 and SW3 are in the “YES” position at the same time)

● A switch to simulate an AC switch failure in open circuit (SW4)

● An STCC08 CNTRL switch (SW5). This switch is used to turn the AC switch (ACS) on

or off through the MCU and the STCC08

● An STCC08 CNTRL LED (D5), used to see whether or not the AC switch has been

controlled by the user

● LEDs to define the ACS state

– A “DIODE” LED (D6) to visualize an ACS failure in diode mode in both AC line

cycles. The LED is on if the AC switch fails in diode mode.

– An “OPEN” LED (D7) to indicate an ACS failure in open circuit. This LED is on if

the AC switch is damaged in open circuit

– A “CC” LED (D8) to show an ACS failure in short-circuit on both polarities of the

AC line. This LED is on if the AC switch is damaged in short-circuit

– An “ON” LED (D9) to indicate that the AC switch is on

● Test points to allow the connection of voltage probes:

– L (TP2) and N (TP1): line and neutral of the AC line – VCC (TP3): positive power supply – GND (TP4): power supply reference – ZVS (TP5): zero crossing of the AC line voltage – OUT (TP6): anode of the ACS – AC (TP7): ACS status sense input – A VF (TP8): alternating voltage feedback. ACS status output – ON/OFF (TP12): “STCC08 CNTRL” switch state, used to turn on or off the ACS

through the MCU and the STCC08

– IN (TP9): STCC08 IN input used to control the ACS

● An AC line connector (J1)

● An AC load: light bulb (15 W at 230 V

RMS

2.1 Block diagram description

Figure 4 shows the block diagr am of th e STCC08. I t inclu des a “gat e d river” block to control

the AC switch, a “pow er switch signal shaping” block used to read the A C s witch stat e 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 situ ations (for example, to open a relay (SW) placed in the front-end of the application - see Figure 5).

Table 1 provides the pin definitions of the STCC08.

Figure 4. STCC08 block diagram description

Figure 5. Application diagram

Note: The STCC08 AVF driver block is used to send the AC switch state to the MCU. The AVF

output is an open collector and should be loaded with an external resistor or connected directly to the MCU, in pull-up input configuration.

2.2 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 curren t con tr olle r

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 ded uced by analyzing the AVF signal. Figure6 gives the ACS state according to the AVF signal state and the IN signal state.

Table 2 gives the AC switch state acco rding to the AVF signal and the MCU control (IN).

Knowing the IN signal state, the MCU is ab le to define the AC switch state by analyzing the AVF signal. According to the failure mode, the MCU can place the system in a safe configuration by switching off the home appliance front-end relay.

Note: “If the AC switch is damaged in short-circuit: the ‘CC’ LED is ON (D8)”

“f the AC switch is damaged only in one direction (diode mode): the ‘DIODE’ LED is ON (D6)”

3 Features

3.1 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

● In the MCU firmware, four options must be set:

– Software watchdog activation – RC oscillator selection – PLL disabled – Low voltage detection selection

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 pow er supply is used on the boar d. One pecu liarity of this DC pow er supply is that it is “negative”. The V

terminal is connected to neutral. This means that the GND voltage is 5 V below neut ral. Such a connection is mandatory to drive the ACS. Indeed, the ACS can only be triggered by a negat ive 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 µF C16 capacitor value has been used to ensure that the board works correctly in the worst application conditions (230 V/110 V

RMS

line voltage ± 10% and VCC ± 10%).

Note that a 43.2 Ω R

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

To reduce the surge current when the bo ard is po w ered, a 39 Ω R1 4 resistor is co nnected in series with the C16 capacitor. Moreover, note that for 110 V

RMS

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.

4.3 Getting started

Warning: The demonstration board is not electrically isolated from the

AC input. The MCU is directl y link ed to the ma ins voltage. No insulation is ensured between the accessible parts and the high voltage. The STCC08 demonstration boar d 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).

● 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

● To turn on the AC switch:

– 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

● To simulate a diode mode of the ACS:

– 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

● To simulate a short-circuit of the ACS:

– 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

● To simulate an open circuit of the ACS:

– 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

● To simulate AC switch failures in any AC load state:

– 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)

● Read the “AVF” test point (TP8) with an oscilloscope connected through an insulated

plug (see example in Figure 9, 10 and 11).

5.1 Test conditions

● Ambient temperature: 25 °C

● Relative humidity: 35%

● Test performed in accordance with IEC 61000-4-4

5.2 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.).

5.3 Recommendations for improving application immunity

To improve application EMC performance, the software must be EMC-oriented (for more information please refer application not e AN1015):

● Auto-recovery 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 V

(data retention parameter). In this case, a complete

startup is not necessary, and t he prog r am can co ntin ue wo rking with the pr e vious RAM

data. This maintains the previous switch state , f or e xample , 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 w atchdog reset or jumps to a kn own prog ram locat ion if y ou do not w ant to generate a reset

● Input filtering. Its recommended to read the AVF signal during several AC line cycles.
