CAT1832 Datasheet Microprocessor

Manufacturer: onsemi

Overview: CAT1232LP, CAT1832 5 V and 3.3 V Supply Monitor, Watchdog Timer, Manual Reset, with Active High & Low.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The CAT1232LP and CAT1832 microprocessor supervisors can halt and restart a “hung-up” or “stalled” microprocessor, restart a microprocessor after a power failure, and debounce a manual/pushbutton microprocessor reset switch.

The devices are drop in replacements for the Maxim/Dallas Semiconductor DS1232LP and DS1832 supervisors Precision reference and comparator circuits monitor the 5 V or 3.3 V system power supply voltage, VCC.

During power-up or when the power supply falls outside selectable tolerance limits, both the RESET and R¯¯E¯S¯E¯T¯ become active.

Key Features

  • Selectable reset voltage tolerance.
  • CAT1232LP for 5 V supply.
  • CAT1832 for 3.3 V supply.
  • Selectable watchdog period: 150 ms, 600 ms or 1.2 s.
  • Two reset outputs.
  • Active high, push-pull reset output.
  • Active low, open-drain reset output (CAT1232LP).
  • Active low, push-pull reset output (CAT1832).
  • Debounced manual push-button reset.
  • Compact SOIC and MSOP packages For Ordering Information details, see page 11. APP.
