It is a high side switch utilizing N-channel vertical power FET technology with integral charge pump. The SSPC provides a status output that signals a variety of conditions including over temperature shutdown, overvoltage or undervoltage, over-current or short circuit. It will trip off for any of the above conditions and automatically (based on an internal thermal time constant) cycle On/Off until the fault or the control signal is removed. Using vertical MOSFET technology, the SSPC offers extremely low “ON” resistance. This results in very low power dissipation, which allows operation over the temperature range of –40°C to +85°C with minimal heat sinking.
