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 TPS3809xxxQ-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.
