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.
