TPS3803−01, TPS3803G15, TPS3805
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 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. The TPS3803 and
TPS3805 devices are characterized for operation over a
temperature range of −40°C to +85°C.

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

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.

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
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
