description (continued)
The TPS3820/3/5/8 devices incorporate a manual reset input, MR. A low level at MR causes RESET to become
active. The TPS3824/5 devices include a high-level output RESET. TPS3820/3/4/8 have a watchdog timer that
is periodically triggered by a positive or negative transition at WDI. When the supervising system fails to retrigger
the watchdog circuit within the time-out interval, t
tout
, RESET becomes active for the time period t
d
. This event
also reinitializes the watchdog timer. Leaving WDI unconnected disables the watchdog.
The product spectrum is designed for supply voltages of 2.5 V, 3 V, 3.3 V, and 5 V. The circuits are available
in a 5-pin SOT23-5 package. The TPS382x devices are characterized for operation over a temperature range
of -40
°
C to 85
°
C.
