53504 latching, isolated output solid state power controllers mii microcircuits division features: ? switch status output ? i 2 t circuit protection with status output ? spst, normally open ? 15a, 20a and 30a operating current ? power fet output with low on-state resistance ? full military temperature operation: -55oc to +125oc. ? radiation hardened capable. ? military environmental screening available applications: ? designed for 24v, 150v and 270v bus applications ? aircraft power distribution ? military/high reliability systems ? satellite/space systems description the 53504 solid-state power controllers are lightweight, resistant to damage from shock and vibration, and immune to contact-related problems (contamination, arcing) associated with mechanical equivalents. transformer coupling between the input, output and power bus stages provides effective isolation of 1000 v rms. the power fet output eliminates bipolar offset and minimizes output voltage drop. the control input is cmos or ttl logic compatible and may operate from a bias supply of 4.5 to 5.5vdc. (see figure 1) integral short-circuit protection, i 2 t trip and output status is provided. the output current flow is continuously monitored and responds to an over-current condition with an i 2 t trip curve by opening the output. over-current conditions include over- load and shorted output during turn-on. an open-collector fault status or output status (optional) is available to indicate the fault or switch state. the output remains blocked until the short is removed and the unit reset. this feature prevents damage to the controller while averting further system failures that may be caused by the short circuit. output fault is an active low output remaining high (open) under all operating conditions except during an output fault. the optional output status is high when the output is on and low when the output is off. resetting the unit is accomplished by recycling the input control. this device is available in various quality levels from cots to class k including any custom screening requirements. 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 output withstanding voltage 2 ..............................................................................................................100, 200, 400 or 500 vdc transient output voltage 3 ?????????????????????????. .....................100, 200, 400 or 500 vdc load current ..................................................................................less than 8 times rated operating current / self limiting bias supply voltage, v dd .............................................................................................................................. ......... -.6 to 5.5 vdc control voltage ................................................................................................................ . 1 volt above v dd / volt below return 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 3 device rating. application derating not included in these values micropac industries cannot assume any responsibility for any circuits shown or represent that they are free from patent infringement. micropac reserves the right to make changes at any time in order to improve design and to supply the best product possible. micropac industries, inc. microcircuits products division ? 905 e. walnut st., garland, tx 75040 ?
