description
TPS3803-01, TPS3803G15, TPS3805
The TPS3803 and TPS3805 families of supervisory circuits provide circuit initialization and timing
supervision, primarily for DSPs and processorbased 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 five-pin SC-70 package.
The TPS3803 and TPS3805 devices are
characterized for operation over a temperature
range of –40°C to 85°C.
