DESCRIPTION
The TLV803 family of supervisory circuits provides
circuit initialization and timing supervision, primarily
for DSPs and processor-based systems.
The TLV803 and TLV863 are functionally equivalent.
The TLV863 provides an alternate pinout of the
TLV803.
During power-on, RESET asserts when the supply
voltage (VDD) becomes greater 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. 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 TLV803
devices are characterized for operation over a
temperature range of 40°C to +125°C.
