SERIAL OUTPUT (SO) PIN REPORTS
Overvoltage
Overvoltage condition reported.
Overtemperature
Fault reported by Serial Output (SO) pin.
Overcurrent
SO pin reports short to battery/supply or overcurrent condition.
Output ON, Open Load Fault
Not reported.
Output OFF, Open Load Fault
SO pin reports output OFF open load condition.
DEVICE SHUTDOWNS
Overvoltage
Total device shutdown at V
PWR
= 28 V to 36 V. All outputs are latched off while the SPI register is reset
(cleared). Outputs can be turned back on with a new SPI command after V
PWR
has decayed below 26.5 V.
Overtemperature
Only the output experiencing an overtemperature condition turns OFF.
Overcurrent
Only the output experiencing an overcurrent shuts down at 1.0 A to 3.0 A after a 70
μ
s to 250
μ
s delay, with
SFPD pin grounded. All other outputs will continue to operate in a current limit mode with no shutdown if the
SFPD pin is at 5.0 V (so long as the individual outputs are not experiencing thermal limit conditions).
