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

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 V

, the TPS3805 devices

provide a second adjustable SENSE input. RESET

asserted in case any of the two voltages drops below V

IT.

During power on, RESET is asserted when supply voltage

becomes higher than 0.8 V. Thereafter, the supervisory

circuit monitors V

(and/or SENSE) and keeps RESET

active as long as V

or SENSE remains below the threshold

voltage V

. As soon as V

(SENSE) rises above the

threshold voltage V

, 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.
