鈥?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 TPS3803 and TPS3805 families of
supervisory circuits provide circuit initialization
and timing supervision, primarily for DSPs and
processor-based systems.
The TPS3803G15 device has a fixed-sense
threshold voltage V
IT
set by an internal voltage
divider, whereas the TPS3803鈭?1 has an
adjustable SENSE input that can be configured by
two external resistors. In addition to the fixed
sense threshold monitored at V
DD
, the TPS3805
devices provide a second adjustable SENSE
input. RESET is asserted in case any of the two
voltages drops below V
IT.
During power on, RESET is asserted when supply
voltage V
DD
becomes higher than 0.8 V.
Thereafter, the supervisory circuit monitors V
DD
(and/or
SENSE)
and keeps RESET active as long
as V
DD
or
SENSE
remains below the threshold
voltage V
IT
. As soon as V
DD (SENSE)
rises above
the threshold voltage V
IT
,
RESET is deasserted
again. The product spectrum is designed for
1.5 V, 3.3 V, and adjustable supply voltages. The
devices are available in a five-pin SC-70 package.
