DESCRIPTION
The 53504 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.
Transformer coupling between the input, output and Power Bus stages provides effective isolation of 1000 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)
Integral short-circuit protection, I2T trip and output status is provided. The output current flow is continuously monitored and
responds to an over-current condition with an I2T 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. 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.
This device is available in various quality levels from COTS to class K including any custom screening requirements. 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.
