TPS3803−01 TPS3803G15 TPS3805H33 www.ti.com SLVS392A − JULY 2001 − REVISED JUNE 2007 VOLTAGE DETECTOR FEATURES APPLICATIONS D Single Voltage Detector (TPS3803): D Applications Using DSPs, Microcontrollers, D D D D D D Adjustable/1.5 V Dual Voltage Detector (TPS3805): Adjustable/3.3 V High ±1.5% Threshold Voltage Accuracy Supply Current: 3 µA Typical at VDD = 3.3 V Push/Pull Reset Output (TPS3805) Open-Drain Reset Output (TPS3803) Temperature Range: −40°C to +85°C 5-Pin SC−70 Package D D D D D D D or Microprocessors Wireless Communication Systems Portable/Battery-Powered Equipment Programmable Controls Intelligent Instruments Industrial Equipment Notebook/Desktop Computers Automotive Systems DCK PACKAGE (Top View) 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.

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.

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 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.
