DESCRIPTION
The TLV809 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 VIT threshold voltage, the output becomes active (low) again. No external components
are required. All the devices in 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 package. The TLV809 devices are characterized for operation over a temperature range of –40°C
to +85°C.
