(Active Low)
Fault Status
The Fail-Safe input pin level determines the state of the outputs after a
watchdog timeout occurs. This pin has an internal pullup.
This input pin is a CMOS logic level input that is used to monitor system
operation.
This output pin is an open drain indication that goes active low when a
fault mode is detected by the device.
of operational power for the device. Pins 4, 26, 27, 58 and 59 must be
shorted together on the board.
These outputs are current and thermal overload protected. Maximum
steady state current through each of these outputs is 500 mA.
These pins serve as the ground for the source of the low-side output
transistors as well as the logic portion of the device. Pins 6, 9, 12 and 15
must be shorted together on the board.
