The Control input is CMOS or TTL logic compatible and the 53506 operates from a bias supply of 4.75 to 5.25VDC. (See

Figure 1)

The part features short-circuit protection, over current protection and an output status pin to monitor the operational state of

the circuit. The output current is continuously monitored to respond to an over-current condition by interrupting the output

current path. Over-current conditions include Load Overload and Short Output (Short Circuit Load) after the device has been

powered up and the load current has been turned on. An open-collector Output Status pin is available to indicate the

“on” or

fault states. The output remains disabled (off) until the fault condition has been removed and the unit has been reset.

Resetting the unit is accomplished by toggling the input control. This feature prevents damage to the controller while averting

further system failure that may be caused by the fault condition.

The 53506 device is available in various quality levels from COTS to MIL-PRF-38534 Class K including custom screening

requirements.

RADIATION TOLERANT

The 53506 contains 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

.
