3 Description
The TPS3809 family of supervisory circuits provides
circuit initialization and timing supervision, primarily
for DSPs and processor-based systems.
During power-on, RESET is asserted when the
supply voltage VDD becomes higher than 1.1 V.
Thereafter, the supervisory circuit monitors VDD and
keeps RESET active as long as VDD remains below
the threshold voltage VIT. An internal timer delays the
return of the output to the inactive state (high) to
ensure proper system reset. The delay time, td(typ) =
200 ms, starts after VDD has risen above the
threshold voltage VIT. When the supply voltage drops
below the threshold voltage VIT, the output becomes
active (low) again. No external components are
required. All the devices of this family have a fixed
sense-threshold voltage VIT set by an internal voltage
divider.
The product spectrum is designed for supply voltages
of 2.5 V, 3 V, 3.3 V, and 5 V. The circuits are
available in a 3-pin SOT-23. The TPS3809xxx-Q1
devices are characterized for operation over a
temperature range of 40°C to 125°C, and are
qualified in accordance with AEC-Q100 stress test
qualification for integrated circuits. For more
