Recommended by Huanian Mall: SLIC interface protection plan. Huanian Mall acts as the agent for the entire series of SOCAY products. Shuokai is a product of ESD, TVS, TSS, etc. SLIC, abbreviated as user interface circuit, refers to the analog user line interface circuit of a programmable switch, which refers to the interface circuit between the switch and the user computer. The analog interface of SLIC is usually a two line telephone line, and the lines are mostly outdoors. At the same time, due to the characteristics of SLICJ itself, it is exceptionally sensitive to external interference. Therefore, it is necessary to provide surge and static electricity protection for SLIC chips.
Application background of SOCAY SLIC interface protection scheme:
1. Global warming, increasing thunderstorms
2. Traditional semiconductor protection solutions cannot achieve external programming
Explanation and precautions for SOCAY SLIC interface protection scheme:
1. Adding two gate controlled transistor trigger circuits on top of traditional semiconductor devices
2.When a common mode forward surge occurs, the diode conducts forward to achieve low clamping
3. When a common mode negative surge occurs, the gate controlled transistor conducts and the semiconductor discharge tube conducts
4. To ensure long-distance transmission, the maximum reference voltage can reach -170V
5. Can withstand 10/700-5/320us combined wave 40A
SOCAY SLIC interface protection application:
1. PBX user level switch
2. VOIP network telephone
3. POTS Traditional Telephone Set
Recommendation for SOCAY SLIC interface protection products:
| category | model | V gkrm | V bat | Ipp | Capacitance | package |
| TSS | TISP61089B | -167 | -170 | 40A | 48pF | SOP-8 |
