The 53514 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. They share the heritage and
features of the 53504 Solid State Controller family.
Transformer coupling between the input, output and Power Bus stages provides effective isolation of 500 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)
Short-circuit protection and I
2
T trip and output status is provided. The output current 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. Standard 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.
These devices contain 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 1 Hz under normal conditions, or into a shorted output.
2. Input transitions should be “bounceless contact” with transitions of <1 ms.
3. System transient suppression must be used to limit switching and fault turn-off current & voltage transients to unit ratings.
