Accelerated Stress Test (HAST) or biased 85/85, temperature
cycle, autoclave or unbiased HAST, electromigration, bond
intermetallic life, and mold compound life. Such qualification

DCK PACKAGE
(TOP VIEW)
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
voltage VDD 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 VDD (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 five-pin SC-70 package.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values are with respect to GND. For reliable operation the device should not be continuously operated at 7 V for more
than t=1000 h.
2. Long term high-temperature storage and/or extended use at maximum recommended operating conditions may result in a reduction
of overall device life. See www.ti.com/ep_quality for additional information on enhanced plastic packaging.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2)
Eco Plan - May not be currently available - please check http://www.ti.com/productcontent for the latest availability information and additional
product content details.
None: Not yet available Lead (Pb-Free).
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean "Pb-Free" and in addition, uses package materials that do not contain halogens,
including bromine (Br) or antimony (Sb) above 0.1% of total product weight.
