CAT810: Voltage Supervisor, Push-Pull, Active High
The CAT810 is a µP supervisory circuits that monitor power supplies in digital systems. The CAT810 is a direct replacement for the MAX810 in applications operating over the industrial temperature range. This device generates 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. The underlying floating gate technology, AE²™ used by ON Semiconductor, makes it possible to offer any custom reset threshold value. Seven industry standard threshold levels are offered to support +5.0 V, +3.3 V, +3.0 V and +2.5 V systems. The CAT810 features a push-pull RESET output (active HIGH). 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. The CAT810 is available in both the compact 3-pin SOT-23 and SC70 packages.
Features- Precision monitoring of +5.0V (-5%, -10%, -20%), +3.3V (-5%, -10%), +3.0V (-10%) and +2.5V (-5%) power supplies
