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.
The TPS3813 family of supervisory circuits provides circuit initialization and timing supervision, primarily for
DSPs and processor-based systems.
During power on, RESET is asserted when 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 = 25 ms typical, starts after VDD has risen above the threshold voltage (VIT). When the supply
voltage drops below the threshold voltage (VIT), the output becomes active (low) again. No external components
are required. All the devices of this family have a fixed-sense threshold voltage (VIT) set by an internal voltage
divider.
