(1) Component qualification in accordance with JEDEC and
industry standards to ensure reliable operation over an
extended temperature range. This includes, but is not limited
to, Highly Accelerated Stress Test (HAST) or biased 85/85,
temperature cycle, autoclave or unbiased HAST,
electromigration, bond intermetallic life, and mold compound
life. Such qualification testing should not be viewed as
justifying use of this component beyond specified
performance and environmental limits.

DESCRIPTION
The TPS3809 family of supervisory circuits provides circuit initialization and timing supervision, primarily for
DSPs and processor-based systems.
During power-on, RESET is asserted when the supply voltage VDD becomes higher than 1.1 V. Thereafter, the
supervisory circuit monitors VDD and keeps RESET active as long as VDD remains below the threshold voltage
VIT. An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset.
The delay time, td(typ) = 200 ms, starts after VDD has risen above the VIT. When the supply voltage drops below
the VIT, the output becomes active (low) again. No external components are required. All the devices of this
family have a fixed-sense VIT set by an internal voltage divider.
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 3-pin SOT-23 package. The TPS3809 devices are characterized for operation over a temperature range of
–55°C to 125°C.
