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, I

output current flow is sensed while under load and while switching, and responds to an over-current with an I

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.
