MOTOROLA ANALOG INTEGRATED CIRCUIT DEVICE DATA

RST
Reset (Active Low)
This input terminal is used to initialize the device configuration and fault registers,
as well as place the device in a low current standby mode. This terminal also starts
the watchdog timeout when transitioned from logic [0] to logic [1]. This terminal
should not be allowed to be at logic [1] until V
DD
is in regulation. This input has an
internal passive pulldown.
35
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.
36
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.
