3引脚微处理器电源监控 3-Pin Microprocessor Power Supply Supervisors
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.The CAT859 and CAT869 feature a push-pull output active low for the two pinout options.The CAT853 and CAT863 feature an open drain RESET output active low. Both require a pull-up resistor on the Fast transients on the power supply are ignored and the output is guaranteed to be in the correct state at VCC levels as low as 1.0 V.
