DESCRIPTION
The 53248 is a 28 VDC Solid State High Side Power Controller (SSPC) that is designed to replace electromagnetic
circuit breakers rated at 10 amperes. 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.
