Surge suppression is a critically important consideration for a variety of commercial and residential electronic systems, as excessive currents can easily cause damage to delicate components. Overvoltage protection ICs, such as the C850-180-WH, are designed to protect sensitive circuits from unexpected surges or spikes of voltage. As a surge suppression IC, this device can be used in a variety of different applications, including industrial equipment, telecom systems, consumer electronic products, and power supplies.

This particular surge protection IC is a P-Channel Enhanced Series MOSFET (PMOS) designed for low voltage protection. It combines the control of a high speed lattice logic circuit with a low resistance MOSFET, allowing the device to rapidly detect and react to incoming voltage levels. The C850-180-WH offers a very low on-state resistance (Rds(on)) of 0.7 mΩ and an extremely low leakage current (2 nA @ 25°C). This makes it ideal for use in low power operations, such as battery-powered devices.

This overvoltage protection IC is also capable of protecting circuits from high-energy transients. Transients are brief, intense, and highly destructive disturbances that can cause severe damage to electronic components. The C850-180-WH is designed to dissipate the energy of these transient events, thereby protecting sensitive components from their harmful effects.

The C850-180-WH surge suppression IC is composed of two main components: a MOSFET voltage station and an overvoltage detection controller. The voltage station acts as a current limiter, ensuring that the IC does not draw too much current during normal operation. The voltage station also helps to limit the amount of voltage that can enter the IC. The overvoltage detection controller monitors the voltage levels of the connected circuit and will activate the MOSFET in the event of a dangerous voltage level.

When the overvoltage detection controller senses a voltage level higher than the preset threshold, it initiates an “interrupt sequence.” This sequence of events causes the MOSFET to quickly change the voltage, dissipating the energy of the incoming transient event and thus protecting the connected circuit. Once the voltage returns to normal, the MOSFET automatically resets and the system resumes normal operation.

The C850-180-WH offers a wide range of features and benefits, including a low operating supply voltage (0.9V-4.4V), low power dissipation (0.7W), and excellent high-speed protection (1.25 nsec response time). The device is also easy to use and is available in a wide range of package sizes, making it suitable for a variety of applications.

The C850-180-WH surge suppression IC is an ideal choice for electronics systems that need reliable, fast protection. This versatile device can be used in a variety of applications – from industrial equipment to consumer electronics – and provides an effective means of thwarting the destructive effects of high-energy transients.
