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.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute–maximum–rated conditions for extended periods may affect device reliability.
NOTE 1: All voltage values are with respect to GND. For reliable operation the device should not be operated at 7 V for more than t=1000h
