The 53507 Series Solid-State Power Controllers are designed to replace electromechanical breakers and solid-state relays.
They overcome the arcing and contamination problems of breakers and provide protection from overload and shorted load
conditions.
Transformer coupling between input and output provides effective isolation of 1000VDC. The Power MOSFET switches
used in the output stage provide low “on” resistance and minimal internal power dissipation.
The Control input is CMOS or TTL logic compatible and is operable from a bias supply of 4.5 to 5.5 VDC. Full specification
performance is from 4.75 to 5.25 VDC.(See Figure 1).
Integral short-circuit protection, I
2
T trip and output status is provided. The output current flow is continuously monitored and
responds to over-load conditions by opening the output with an I
2
T trip curve. An open-collector Output Status or (optional)
Fault Status is provided. When tripped, the output remains blocked averting further system damage. Status is an open
collector output High with an ON SSPC and Low with an OFF SSPC (Command OFF or Faulted). The optional Fault Status
is an open collector high (Open) for all SSPC conditions except Faulted. Resetting the unit is accomplished by cycling the
input control.
A Trip current adjust is provided to allow customer trimming of the trip current between the design
I
trip
and one half of
I
trip
.
Connecting Pins 3 and 8 will reduce the “Steady State Trip Current” by one half without changing the “Instant Trip” let-
through current. An intermediate trip point may be achieved by connecting a resistor per the following between Pins 3 and 8.

RADIATION TOLERANT:
The 53507 contains radiation hardened components and / or other features that provide a level of radiation tolerance.
Micropac does not offer this device as compliant to Appendix G (RHA Requirements) of MIL-PRF-38534, and does not
guarantee any level of radiation hardness. Specific lot testing is required to determine the level of radiation hardness.
PRECAUTIONS:
SSPC’s must always be operated with adequate transient voltage protection. When the SSPC turns off rapidly due to
overload or fault conditions, external wiring impedance may generate transient voltages when current is interrupted. The
resultant voltages and currents must not exceed the published Maximum ratings of the SSPC.

1. Selected output is determined by connecting either or both outputs to the output sense (Pin 8).
APPLICATION NOTES:
1. Maximum input switching frequency not to exceed 1 Hz under normal conditions, or into a shorted output.
2. Input transitions must be “bounceless contact” with transitions of <1 ms.
3. Inductive loads must be suppressed.

is present.
Bus power-up with Control and Control power ON requires a Control OFF and ON to turn the Unit On.
A turn-on into an overload results in a shutdown defined by time and current expressed in Figure 5.
Turning on into a shorted load may cause damage.
