5-Pin SC−70 Package
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 5-pin SC-70
package.

(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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible
to damage because very small parametric changes could cause the device not to meet its published specifications.

(1) 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.
(2) 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.
(3) 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)
RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
