DESCRIPTION

The 53513 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 53503 Solid State Controller family.

Transformer coupling between the input, output and Power Bus stages provides 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

to an over-current condition with an I

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.
