CAT859 Overview
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
