3 Description

The TLV809 family of supervisory circuits provides

circuit initialization and timing supervision, primarily

for digital signal processors (DSPs) and processor-

based systems.

During power-on, RESET is asserted when the

return of the output to the inactive state (high) to

(low) again. No external components are required. All

devices in this family have a fixed sense-threshold

The TLV803 has an active-low, push-pull RESET

output. See the TLV803 for an open-drain RESET

output and the TLV810 for a push-pull, active-high

RESET output.

This product family 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.
