Bias Supply- External 5V power supply used to power the SSPC inter-
nal circuitry.
BIT- Built In Test.
Coordination- If one or more SSPC's are placed in a series circuit, the
SSPC with the lowest rated current will trip first during an over cur-
rent condition.
Dielectric Strength- The breakdown voltage rating, in Vrms, of an elec-
trical isolation barrier.
EMI- Electromagnetic Interference.
I2T- Expression that evaluates to a constant value. This constant defines
the trip time of the SSPC for any over current except those that would
cause an instant trip.
Instant Trip- Condition where the SSPC trips immediately without fol-
lowing the I2T curve. This occurs when the SSPC load current
exceeds a predefined value.
Isolation- The D.C. resistance of an electrical isolation barrier, mea-
sured with a known D.C. potential.
Leakage Current- The current that flows into the load when the SSPC
is in the off state.
Lockout Control- Provides safe maintenance. When the lockout control
is in the active state, the SSPC must be off and shall not respond to
the control input.
Max Load Capacitance- Exceeding this load capacitance value may
cause unwanted tripping.
MOSFET- Metal Oxide Semiconductor Field Effect Transistor.
On Resistance- Effective resistance in ohms of the SSPC between the
Power In and Power Out pins when the SSPC is turned on.
Power Dissipation- Power in watts dissipated by the SSPC. Measured
as ( VBias x IBias ) + ( Voltage Drop x Load Current ).
Rated Current- Maximum load current where the SSPC will operate
continuously without tripping.
SSPC- Solid-State Power Controller
Sympathetic Tripping- Where any SSPC in a system can cause any
other SSPC in the system to trip abnormally. ( ie. Path through FET
parasitic diode or induction transients ) Sympathetic tripping is not
desirable.
Thermal Resistance- A measure of resistance to heat transfer. Allows
calculation of a device’s temperature rise above its mounting surface.
Specified in °C/W.
Thermal Memory- The ability of an SSPC to account for the thermal
energy retained in a wire or device.
Voltage Drop- Maximum voltage measured between the Power In and
Power Out pins with the Power Controller operating at its Rated
Current.
