† 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.

NOTE 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.

The TPS3803 and TPS3805 families of supervisory circuits provide circuit initialization and timing supervision, primarily for DSPs and processorbased systems.

In the TPS3803 and TPS3805 families ,the TPS3803G15 device has a fixed-sense threshold voltage V_IT 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_DD, the TPS3805 devices provide a second adjustable SENSE input. RESET is asserted in case any of the two voltages drops below V_IT.

During power on, RESET is asserted when supply voltage V_DD becomes higher than 0.8 V. Thereafter, the supervisory circuit monitors V_DD (and/or SENSE) and keeps RESET active as long as V_DD or SENSE remains below the threshold voltage V_IT. As soon as V_DD (SENSE) rises above the threshold voltage V_IT, RESET is deasserted again. The TPS3803 and TPS3805 families  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. The TPS3803 and TPS3805 devices are characterized for operation over a temperature range of −40 to 125.
