DESCRIPTION
The TLV810 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 (low) 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 (high) 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 TLV810
devices are characterized for operation over a
temperature range of 40°C to +125°C.
