DESCRIPTION

The TLV809 family of supervisory circuits provides circuit initialization and timing supervision, primarily for DSPs

and processor-based systems.

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.
