DESCRIPTION
The 53282 is a derivative of the 53278 SSPC. It shares core circuits and components tested for Total Dose and Single Event Effects. The 53282 has Non-latching Control and the Power Bias is powered from 5V logic power. The 53282 is a lightweight device resistant to damage from shock and vibration and is immune to contact-related problems (contamination, arcing) associated with mechanical equivalents. Transformer coupling between the input and output stages provides effective isolation up to 1000 V RMS. The Power FET output eliminates bipolar offset and minimizes output voltage drop. The preferred control input is CMOS compatible operating from a bias supply of 4.5 to 5.5VDC. (See Figure 1) Integral short-circuit protection, I2T trip and status output is provided. This unit is Pin configurable for 1A or 2A output. The output current flow is sensed while under load and while switching, and responds to an over-current with an I2T trip curve by opening the output. An open -collector Status is available to indicate the switch state. The output will remain blocked indefinitely until the short is removed and the unit reset. 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. This device is 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-38534 with no element evaluation or QCI. Radiation Tolerant This device contains radiation hardened components and / or other fe atures that provide a level of radiation tolerance. Micropac does not guarantee any level of radiation hardness. Specific lot testing is required to determine the level of radiation hardness. Micropac does not offer this device as compliant to Appendix G (RHA Requirements of MIL-PRF-38534.

Maximum input switching frequency not to exceed 20 Hz under normal conditions, or 1 Hz if output is shorted. 2. Input transitions should be <1 ms and duration and input source should be “bounceless contact” type. 3. Inductive loads must be suppressed. 4. Peak current that may flow when output is shorted.
