33800
FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
No Operation Command
Sending these two commands perform no operation. The device outputs will remain in previous state.
.
Table 23. No Operation Command
FAULT OPERATION
On each SPI communication, a 16-bit command word is
sent to the 33800 and a 16-bit status word is received from
the 33800.
The Most Significant Bit (MSB) is sent and received first.
Command Register Definition:
0 = Output Command Off
1 = Output Command On
SO Definition:
0 = No fault
1 = Fault
SPI Command Summary

Serial Output (SO) Pin Reports
Over-current
SO Pin reports short-to-battery/supply or over-current condition.
Output ON Open Load Fault
Not reported on GDX and OUTX outputs. Reported on CCD1 and CCD2 outputs
Output OFF Open Load Fault
SO Pin reports output “OFF” open load condition.
Device Shutdowns
Over-voltage
Total device shutdown at V
PWR
= 36.5 to 44V. Resumes normal operation with proper voltage. Upon
recovery all outputs assume previous state or OFF based on the over-voltage bit in the Shutdown Retry
Control register.
Over-current
OUTX & CCDX outputs will remain in current limit until t
SC
limit is reached. With TLim enabled, OUTX &
CCDX outputs will remain in current limit until TLim is reached.
