Surge suppression ICs - C850-260-WH application field and working principle

The C850-260-WH is a surge protection IC designed to protect costly electronic components and systems from destructive transient voltages. It is a model of ICs used in surge suppression commonly referred to as "over-voltage protection ICs." In this article, we will discuss the application field of C850-260-WH and its working principle in detail.The surge suppression ICs or "overvoltage protection ICs" are used to protect delicate electronic components from excessive surge voltages. These ICs are especially useful in scenarios where the power delivery system may be subject to large transient voltages such as power fluctuations, lightning strikes or power glitches. The C850-260-WH can be used in many applications, including automotive systems, industrial machinery, electronic control systems, consumer electronic systems and UPS systems, among others.The C850-260-WH has a built-in voltage reference, which enables it to precisely detect the incoming voltage amplitude. The IC then triggers a clamping circuit, which cuts off the power supply immediately and starts diverting the excessive voltage away from the electronic components. This enables quick response time, which is extremely important for ensuring the safety of the electronic components. Furthermore, the IC also has over-voltage protection features to prevent the circuit from being damaged due to a long-term over-voltage.The C850-260-WH combines MOSFETs and transient voltage suppressors (TVS) to provide surge protection for a wide range of applications. The IC has two independent MOSFETs, one for powering the load and the other for triggering the clamping circuit. The clamping circuit acts like a switch which turns off the power supply whenever there is an over-voltage. The IC also has two TVSs which are used to divert the excessive voltage away from the load and protect it from any further damage.The C850-260-WH is designed to handle with +8.2V/−12V surges. The clamping voltage (Vclamp) of the IC is adjustable between 6V and 12V, which allows for customization depending on the specific application. The IC is rated to handle with up to 70kA of surge current, which makes it highly suitable for harsh environments where large transient voltages can occur.In addition to surge protection, the C850-260-WH also offers short-circuit protection and over-voltage protection features. When the IC detects a short-circuit or an over-voltage condition, it triggers the MOSFET power switch to disconnect the power supply immediately and protect the circuit from any further damage. The short-circuit protection feature can be enabled/disabled using the appropriate pin.To sum up, the C850-260-WH is an ideal surge protection IC for automotive systems, industrial machinery, electronic control systems, consumer electronic systems, and UPS systems. It is suitable for harsh environments and is rated to handle with up to 70kA of surge current. The IC also offers short-circuit protection and over-voltage protection features which make it an excellent choice for protecting delicate electronic components and systems from transient voltages.
