CAT8801:200 nA Microprocessor Power Voltage Supervisor
The CAT8801 is a supervisory circuit that monitors power supplies in digital systems and provides a reset signal whenever the system's input voltage is below a prescribed minimum level. The CAT8801 replaces popular voltage supervisors such as MAX809 in applications where operating current is a primary consideration. CAT8801 generates a reset signal, which is asserted while the power supply voltage is below a preset threshold level and remains asserted for at least 140 ms after the power supply level has risen above that level. Nine industry standard threshold levels are offered to support +5.0 V, +3.3 V, +3.0 V, +2.5 V and +1.8 V systems. ON Semiconductor's floating gate technology, used in programming the trigger thresholds, makes it possible to quickly offer any custom reset threshold value should the 9 standard voltage thresholds not meet a system's needs. The CAT8801 features a Push-Pull CMOS RESET output (active LOW) and is fully specified over the industrial temperature range of -40°C to 85°C. CAT8801 is available in compact 3-pin SOT23 and SC-70 packages.
