description (continued)
When the supply voltage drops below the threshold voltage V
IT
, the output becomes active (low) again. No
external components are required. All the devices of this family have a fixed-sense threshold voltage V
IT
set
by an internal voltage divider.
The TPS3123-xx and TPS3125-xx devices incorporate a manual reset input, MR
.
A low level at MR causes
RESET
to become active. The TPS3124-xx devices do not have the input MR, but include a high-level output
RESET same as the TPS3125-xx devices. In addition the TPS3123-xx and TPS3124-xx have a watchdog timer
that need to be triggered periodically 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
= 0.8 s, RESET output becomes active for
the time period t
d
. This event also reinitializes the watchdog timer.
The circuits are available in a 5-pin SOT23-5 package. The TPS3123, TPS3124, TPS3125 devices are
characterized for operation over a temperature range of –40
°
C to 85
°
C.
