SERIAL OUTPUT (SO) PIN REPORTS
Over-voltage
Over-voltage condition reported
Over-temperature
Fault reported by Serial Output (SO) pin
Over-current
SO pin reports short to battery/supply or over-current condition
Output ON, Open Load Fault
Not reported
Output OFF, Open Load Fault
SO pin reports output OFF open load condition
DEVICE SHUTDOWNS
Over-voltage
Total device shutdown at VPWR = 28 to 36V. All outputs are latched off while the SPI register is reset (cleared).
Outputs can be turned back on with a new SPI command after VPWR has decayed below the over-voltage
shutdown voltage including hysteresis.
Over-temperature
Only the output experiencing an over-temperature condition turns off.
Over-current
Only the output experiencing an over-current condition shuts down at 3.0A to 6.0A after a 25ms to 100ms delay,
with SFPD pin grounded. All outputs will continue to operate in a current limit mode, with no shutdown, if the
SFPD pin is at 5.0V.
