A5348 - Ionization Smoke Detector

Download the A5348 datasheet PDF. This datasheet also covers the A5348CA variant, as both devices belong to the same ionization smoke detector family and are provided as variant models within a single manufacturer datasheet.

General Description

The A5348 is a low-current, BiCMOS circuit providing all of the required

Key Features

  • Low average standby current for long battery life.
  • Interconnect up to 125 detectors.
  • Piezoelectric horn driver.
  • Guard outputs for detector input.
  • Pulse testing for low battery.
  • Power-on reset (POR).
  • Internal reverse battery protection.
  • Timer (Hush) mode for enabling reduced sensitivity period.
  • Built-in hysteresis reduces false triggering.
