rev 1 november 2005 1/13 13 vn540-e / vn540sp-e VN540-12-E single high side smart power solid state relay general features output current (continuous) : 2.8a digital input clamped at 32v protection against: ? loss of ground ? shorted load and over- temperature built-in current limiter undervoltage shut-down open drain diagnostic output fast demagnetization of inductive loads description the vn540-e, vn540sp-e, VN540-12-E are monolithic devices designed in stmicroelectronics vipower technology, intended for driving resistive or inductive loads with one side connected to ground. active current limitation avoids the system power supply dropping in case of shorted load. built-in thermal shut-down protects the chip from overtemperature. the open drain diagnostic output indicates over- temperature conditions. type v demag r dson i out v cc vn540-e vn540sp-e VN540-12-E v cc -55v 50m ? 2.8a 36v pentawatt(012y ) pentawatt powerso-10 tm www.st.com block diagram
