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, I
2
T 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 I
2
T 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 features 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.

APPLICATION NOTES:
1. 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.

Notes
1: Unit Powers up in the Off condition independent of Bus Power or V

sequence.
2: Fault Status reports only when V
DD
is present.
3: Control “0” Off must be invoked upon applications of 5V and Bus Power for an unambiguous output
and fault status.
4: An Off Control to On Control transition is required to first turn the Unit On.
5: Loss of V

will cause an output Off condition.
