Description

General part information

TPS3805H33-EP Series

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 VITset 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.RESETis asserted in case any of the two voltages drops below VIT.

During power on,RESETis asserted when supply voltage VDDbecomes higher than 0.8 V. Thereafter, the supervisory circuit monitors VDD(and/or SENSE) and keepsRESETactive as long as VDDor SENSE remains below the threshold voltage VIT. As soon as VDD(SENSE) rises above the threshold voltage VIT,RESETis 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.
