CAT859 Description

The CAT853, CAT863, CAT859, and CAT869 are supervisory circuits that monitor power supplies in digital systems. These devices generate a reset signal, which is asserted while the power supply voltage is below a preset threshold level and for at least 140 ms after the power supply level has risen above that level. Industry standard threshold levels are offered to support +3.3 V or 5.0 V systems.

CAT859 Key Features

  • Precision Monitoring of +3.3 V (-5%, -10%)
  • Active Low Reset Output
  • Reset Valid down to VCC = 1.0 V
  • 6 mA Power Supply Current
  • Power Supply Transient Immunity
  • Industrial Temperature Range: -40°C to +85°C
  • SOT-23 Package
  • These Devices are Pb-Free and are RoHS pliant
