DESCRIPTION
The 53506 Series Solid-State Power Controllers (SSPC) are designed to replace electromechanical breakers and solid-state
relays. In addition to less weight and resilience to shock and vibration damage, SSPCs offer superior performance and
longer operational lifetime over electromechanical circuit breakers, by eliminating problems associated with arcing and
contact contamination. 53506 SSPCs also offer protection for current overload and short circuit conditions.
Control input and output stages are isolated up to 1000VDC. The Power MOSFET switches used in output stage provide low
“on” resistance and minimal internal power dissipation.
Micropac recommends that any transient voltage which may result from operating into an inductive load (i.e. during turn off)
should be suppressed to ensure that the part will not be exposed to a condition above its absolute maximum ratings.
The 53506 SSPC features a programmable current trip point feature, allowing the trimming of the trip current between the
device current rating ( I _trip ) and one half of I _trip . The trip point can be adjusted per the following equation:
    I  I _(trim)
( d esig n)
1  ⁵⁰
100  R_(trim)
Where R_(trim) is in kilo ohms. As an application example, R_(trim) must be set to zero ohms, for a 50% current trip point. This
can be accomplished by applying a short circuit between pins 6 and 7 of the device.
