(see figure 1) integral short-circuit protection, i 2 t trip and output status is provided. this 100v unit is pin configurable for 1a or 2a output and the 250, 400 and 500v units are set to 1 or 2a output. the output current flow is sensed while under load or while switching, and responds to an over-current with an i 2 t trip curve by opening the output. an open-collector output status is available to indicate the switch state. the output will remain blocked indefinitely until the short is removed and the unit re set. this feature prevents damage to the controller and also averts further system failures that may be caused by the short circuit. output status is on (high) when the output is switched on and is off (low) whenever the output is commanded off or tripped. resetting the unit is accomplished by recycling the input control. these devices are available in a variety of quality levels from cots to class k including any custom screening requirements and all components have radiation-hardened equivalents. the basic data sheet part is environmentally screened to h level in accordance with table c-ix of mil-prf-38 534 with no element evaluation or qci. absolute maximum ratings isolation voltage 1 ............................................................................................................................... ........................1000 v rms continuous operating output voltage 2 ................................................................................................100, 250, 400 or 500 vdc transient output voltage?????????????????????????????? .....100, 250, 400 or 500 vdc load current ................................................................................................................... ................................. 18a / self limiting bias supply voltage, v dd .............................................................................................................................. ........ 4.5 to 5.5 vdc operating temperature ......................................................................................................... ................... -55oc to +125oc case storage temperature ........................................................................................................... ...............................-55oc to +125oc notes : 1 60 hz sine wave 2 reversing polarity on the output may cause permanent damage
