A5303 Product details

Description

The A5303 is a low-current BiCMOS photoelectric smoke detector circuit with ultra-low standby current and can operate for 10 years powered by inexpensive batteries.

Features

▪ Low average standby current allows 10-year battery life ▪ 2.3 to 5.5 V operating range ▪ Interconnect option ▪ Logic outputs to control an external sound IC ▪ Low battery detection and warning ▪ Chamber sensitivity test and warning ▪ Triple horn-chirp to distinguish chamber warning ▪ Power-on reset (POR) ▪ Digital filter on I/O provides significant noise immunity ▪ Timer (hush) mode for enabling reduced sensitivity period ▪ Built-in circuits to reduce false triggering ▪ ESD protection circuitr.
