(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 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
VIT set by an internal voltage divider, whereas the
TPS3803−01 has an adjustable SENSE input that can be
configured by two external resistors. In addition to the fixed
sense threshold monitored at VDD, the TPS3805 devices
provide a second adjustable SENSE input. RESET is
asserted in case any of the two voltages drops below VIT.
During power on, RESET is asserted when supply voltageDD becomes higher than 0.8 V. Thereafter, the supervisory
circuit monitors VDD (and/or SENSE) and keeps RESET
active as long as VDD or SENSE remains below the threshold
voltage VIT . As soon as V (SENSE) rises above the
threshold voltage VIT , 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 5-pin SC-70
package.
