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
TPS380301 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.
