CAX803 - 3-Pin Microprocessor Power Supply Supervisors

General Description

monitor power supplies in digital systems.

The CAX803, CAX809, and CAX810 are direct replacements for the MAX803, MAX809 and MAX810 in applications operating over the industrial temperature range.

Key Features

  • a push.
  • pull RESET output (active LOW) and the CAX810 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 CAX803, CAX809, and CAX810 are available in the compact 3.

CAX803, CAX809, CAX810 3-Pin Microprocessor Power Supply Supervisors Description The CAX803, CAX809, and CAX810 are supervisory circuits that monitor power supplies in digital systems. The CAX803, CAX809, and CAX810 are direct replacements for the MAX803, MAX809 and MAX810 in applications operating over the industrial temperature range. 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. The underlying floating gate technology, Analog EEPROM 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.
