1
FSI
Fail-Safe Input
The Fail-Safe input terminal level determines the state of the outputs after a
watchdog timeout occurs. This terminal has an internal pullup. If the FSI terminal is
left to float to a logic [1], then HS0 and HS2 will turn on when in the Fail-Safe state.
If the FSI terminal is tied to GND, the watchdog circuit and fail-safe operation will be
disabled, thus allowing operation without a watchdog signal.
2
WDIN
Watchdog Input
This input terminal is a CMOS logic level input that is used to monitor system
operation. If the incoming watchdog signal does not transition within the normal
watchdog timeout range, the device will operate in the Fail-Safe mode. This input
has an active internal pulldown.
3
FS
Fault Status
(Active Low)
This output terminal is an open drain indication that goes active low when a fault
mode is detected by the device. Specific device fault indication is given via the SO
terminal.

V
PWR
Positive Power Supply
These terminal connects to the positive power supply and are the source input of
operational power for the device.

Low-Side Output 4
Low-Side Output 6
Low-Side Output 8
Low-Side Output 10
Each low-side terminal is one 0.6
low-side output MOSFET drain, which pulls
current through the connected loads. Each of the outputs is actively clamped at
53 V. These outputs are current and thermal overload protected. Maximum steady
state current through each of these outputs is 500 mA.
6, 9, 12, 15
GND
Ground
These terminals serve as the ground for the source of the low-side output
transistors as well as the logic portion of the device.
