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 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 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.
